SQL 2012 :: High Memory Usage On Idle Reporting Services
Aug 25, 2015
I know I should probably be posting this in the RS section but I have a Win 2008 R2 server and RS 2012 along with SSIS and Database server installed. I also have SQL 2005 instance with Sql 2005 SSIS running on the server.
I saw that Reporting services was consuming 9gb of ram a few days ago with no published reports. It's just a default install.
So I investigated the settings and the document: [URL]......
I added this section to the reportserver.config file to restrict memory usage
windows is sql server 2012 64 bit edition and sql server is 2012 64 bit edition.
RAM installed on both server is around 65 gb of which 49 gb is max server memory allocated for sql services on both servers.
database related to reporting services are also in always on group .
We have also configured for reporting services and both are running on their respecting server.
Issue is on primary server reporting service is using almost 7 gb while on secondary it is using 10 gb even when there are 5 reports and its used within offices .
what issue and how to check why ssrs is using high memory..
any query , perfmon counters
reports are randomly used at client side
i have checked memory utilization through task manger..
I have been having issues with our SQL server for awhile now. It seems to run out of memory every few days and when I look at the memory dump, the MEMORYCLERK_SQLOPTIMIZER seem to take over memory and eventually cause the server to crash.
Here is the SQL verison we are using: Microsoft SQL Server 2012 (SP1) - 11.0.3460.0 (X64) Jul 22 2014 15:22:00 Copyright (c) Microsoft Corporation Enterprise Edition (64-bit) on Windows NT 6.2 (Build 9200: ) (Hypervisor)..It is on a VM on Windows 2012 server. It has 20gb of RAM allocated to it and the MAX Server Memory is set to 16.5gb.
I have seen the MEMORYCLERK_SQLOPTIMIZER grow to about 11gb at the time of the server crash. Why that is happening? What is causing the memoryclerk_sqloptimizer to get so high? I have looked it up and it looks like it has to do with ad hoc requests, but is there something I can do to bring that memory down when it gets so high so that I can prevent a server crash?Do we just need to add more memory or is there a memory leak somewhere?
I got a small MSSQL server.. total database file size less than 7GB. with 2G rams installed 2 cpus. but for some reason when i check the task manager process mem usage is over 1.7G. the sql server memory setting in on Dynamically not fixed. and maximum 2G i believe is default. anyway. my question is over 1.7 memory usage is too high? because i dont have alot of transaction going. and cpu usage is very low. wondering if this's normal or not. and if is not normal . what cause the memory usage so high...... and how can i adjust back to normal. ? can anyone help me out? or any suggestion? thanks
I am trying to find out what could be causing this issue. Why would we be waiting on cpu when its barely being used. Signal waits are varying from 35 to 55% and cpu usage is only at 5% usage.We are using Windows Server 2012 with SQl Server 2012 Standard edition with cpu5. There are 3 instances on the server each with max memory 50gb memory and the server has a total of 190gb memory. The machine is a 12 core machine with hyperthreading enabled.
We have a system(32GB RAM and 2 TB hard disk, Windows7,SQL SERVER 2008R2 enterprise 64 bit). Looks like whenever i run some query(even query result 50 records) on the database, the Memory utilization is very high(30 GB) in task manager. How can i control this over usage? The memory setting is default in server properties(min 0 and max 2147483647).
I have around 100 packages (all [packages run at same time) each package calls a stored Procedure once the Stored proc Execution is completed the package will write the log information into a log table, here how can i capture the CPU and Memory usage for execution of each stored proc.
Hello, we have a customer-facing ASP.NET web reporting application that allows the user to a). select a report b). make report settings (filter, sort, include/exclude columns), and c). run the report. An Oracle stored proc is used to return the data into a DataSet. Today the output is displayed in a bound, paginated DataGrid.
We€™d like to €˜plug-in€™ Reporting Services for improved formatting, grouping, matrix reporting, drilldown, graphics, etc.. I have read through the online docs, examples, and tutorials but have not found the exact (high-level) information I€™m looking for.
We need to keep our report settings page, Oracle SP architecture, etc... Is there a way to simply hand off a dynamically created DataSet to a report for display €“ like binding to the DataGrid? The data (query) would be specific to a report but columns can be selected/unselected for display. In terms of deployment, is it necessary to install SQL Server in each environment (DEV-Integration, QA, PROD) to support Reporting Services? Since we are essentially an Oracle shop, this could be a tough sell. Is it possible to develop the report on a dev workstation (perhaps with SQL Server), and then publish to a web server where SQL Server is not installed?
These are obviously high-level questions - any help will be appreciated (examples, how-to's, etc..) €“ thanks in advance. -Bill
In our production environment there are 200+ reports are running developed by me only , which are again used by 1500+ employees as it is finance domain itself .

I have a client program that writes to sql server database 10 records per second . i want to compute the CPU usage and the memory usage for the whole program or CPU usage,memory usage for the insert statement in the program .
In my report I have two parameters PID and patientName, but user want to enter either PID or patientName. When I preview the report user can only enter one parameter not both. Is there any way  to create two parameter available but users can enter only one parameter value?Here is my report layout and query I used for that report. These two parameters comes from one column 'String_NVC' as from query and column name 'Description' as from the report layout.
SELECT Username_NVC AS Username, String_NVC, Time_DT AS UserActionDateandTime, FROM test
What can be the reason there is a high CPU usage even when there's only 1 database being accessed. As a result the database is really really slow. CPUperformance usage goes as high as 100% and I can't for the life of me figure out what's causing it. The indexes are being rebuilt 3/4 times a week and I've checked to make sure there aren't any locks or anything.
We have a live server that has had very high CPU usage in the last few days, therefore the site is extremely slow. There are about 60,000 users per day on the average. It always had high CPU usage, but not as bad as in the last few days, in the 90s, sometimes even reaching a 100.
Any solutions? I've run SQl Profiler to check on queries that have high CPU usage. When I run the same queries on our staging server, they are very quick. For example, the same query can take 1 minute on stage, but 12 minutes on the live site. We do know that this is also related to traffic, during lower traffic times, the same query takes less time, but still never as fast as stage.
Oh yeah, it's SQL Server 2005 and asp code running IIS6 on windows 2003 server.
I have a Windows sever 2012 with sql server 2012 enterprise. Ram size is 22GB. Sometimes SQL sever takes 95% memory.My question, How to reduce memory size without killing any process because it's production server.So there are many background process is running. And,Is there any guides to learn why Memory is raise d so high and how to reduce it.
We have SCCM 2012Â primary site and Remote SQL 2012 server. Due to hardening and password reset we are facing reporting issue.
while we Open the SRS report in SQL server and try to edit the Report (Report Builder) we are getting following error due to which we are unable to configure Reporting Service point in the SCCM 2012 server. We created the New Reporting server database still we are getting the below error.
I have an sql server with very high usage. The web which is connected to the sql server has approx. 1000 unique visitors every time. The database is optimized and the site goes really fast now.
But a problem we've had since the beginning is that SQL Server constantly uses 1.8 GB of RAM. Never less, never more.
Do you have any idea on how to decrease the usage of RAM. I am sure that this high usage is necessary.
For the last week, our production SQL server is running very slow and causing the CPU usage to go 80-100 % almost all the time. This causes certain queries to time out. Our application has never timed out before ever. Also, we did not do any updates on our production machine or installed anything recently.
Has anyone of you ever experienced this issue? If yes, then what did you do to resolve it? any help would be greatly appreciated.
I have a problem with sqlservr.exe (version 2005). It use alot of memory. I check on taskbar manager sqlservr.exe usage (CPU 10 - 20%, Mem usage - 1,493,688/2GB Ram). I dont know how can I fix it. Some body could help me please.

Anyone aware of anything I can look at to improve performance of my SSIS packages? i basically have two master packages that call about 15 child package tasks each. All the package tasks are called sequentially and all they do is just load flat files into temporary tables and execute a simple stored proc. Each package tasks check to see if a file is there and if so it processes it else it just ends. The packages are scheduled to run every minute to check for files. If I watch the CPU during execution i can see the two instances of DTSEXEC.exe running and consuming about 25-30% of the CPU. The box that this runs on is a Quad processor with 4 GB of ram.
Any ideas on how to improve the performance of this? I have tried playing with the transaction level, but that didn't seem to do much performance wise.
Just built a new DB server. Using SQL2K5Standard 64bit on W2K3Server 64bit. Hardware includes 16GBs memory/dual 4-core procs and many spindles, however we only have a 2GB page file on C:. SQL is set to to usa a maximum of 12GB memory which is way more than it should need. Problem is, we are occasionally seeing very high page file usage. If Task Manager is correct, (which it really can't) I am using 10 and 13.8GB (as listed in PF Usage) But I only have a 2GB page file! Occasionally when simply copying a file from one partition to another, PerfMon shows Pages/sec jump to 10,000. Also see some very high Disk Queueing.This system isn't even in production yet. My main questions are two: 1) some documentation says with SQL2K5-64 bit running on W2K3-64bit I may not even need a page file. Is this correct? 2) What would be causing high usage of the swap file with 16GBs of installed memory? And help would be appreciated. Thanks in advance!
I have six stored procedures that I have to run hourly during the day. When I schedule them into separate SQL jobs (they must run concurrently), the percent CPU of Sqlagent90.exe process goes way up, eventually pegging out the overal CPU usage on the server. When I run the six stored procedures concurrently from query windows in SQL Server Management Sudio, the overall CPU usage stays very low.
Is there something about the SQL Server Agent that inherently adds CPU overheard? Thanks in advance ....
I am working on a serial tracking application using Sql Server 2005 and .Net. One of the requirments is to have an ad-hoc file export utility in which users can drag-n-drop fields from a set of tables and export the results to CSV. It all sounds ok and Sql Server Reporting Services' Report Builder seem to be just the right tool for it, but there is one problem : The report size is big, about 7K - 8K pages and 4 - 5 columns wide; while rendering the report, IIS memory usage shoots up to about 2GB and remains at about 2GB. Any idea if something can be done to mitigate this problem? Note that I dont need the HTML rendering at all. All I need is to have the CSV at the end of the day, while users are able to chose columns in an ad-hoc manner.
Hello sql and .net gurus :-)I have a problem with my website www.eventguide.it. It's completly developed under .NET 2 and SQL Server 2005 Express. My problem is the folowing:The server is a Intel 3Ghz HT processor with 1GB Ram. No other page on the running system is a CPU consuming site. We optimized the SQL statements, the code, the caching and many other parts of the website (pooling on SQL access), but the SQL Server uses about 50% to100% of the CPU and about 400MB RAM all the time. The whole site seems to be very, very slow. In fact there are many of SQL operations on every page request, but we cache a lot of them in different ways (page output caching, application caching). So I don't understand we have so much performance problems. Any suggestions for optimised code in general? I read nearly all of the MS .NET performance papers - but real world experience is the missing part :-) It is better to cast the values of a SQL reader like thisDim String1 as String = Ctype(DataReader.item(0), String)Dim Integer1 as Intger = Ctype(DataReader.item(1), Integer)or like thisDim String1 as String = DataReader.item(0) Dim Integer1 as Intger = DataReader.item(1)Thanks a lot for your help!FOX
I have a few in house developed application (VB based) that access the SQL server for adding, appending , creating tables. The application does the changes thru queries dynamically generated at the application level.
My MS SQL Server runs on a PIII / 256 MB Ram / 18 GB HDD
The problem is that the memory utilization of SQL server keeps growing constantly. Out of 512 MB (256 Physical + 256 Virtual) available teh memory utilization reaches a level of 490 MB and statys constant. Though SQL Server shows a utilization of 150 MB.
I suspect that SQL is not releasing memory back to the system. Please help in resolving. The problem may lie at the applications developed.
I have a 2003 server with sql 2005 on it and the sqlservr.exe is using 880 meg of memeory and it will climb to 1.4 gig. if i reboot server it will go back to 100 meg and slowly climb back up. any ideas i am not a sql guy.
Getting old favourite message 'Out of Memory' when running a horizontal clustered chart with Category: 200 items Series: 200 items per Category.URL... 'By default, the report server sets WorkingSetMaximum to the amount of available memory on the computer. This value is detected when the service starts.'Â
The report has been tried on 3 large servers with 30GB & 60GB memory. The report runs on a 2008 install but not a 2008R2 install. We've created a test report that simply generates a series of data 1-n for Category and 1-n for Series where n can be set by parameter - so the issue is not to do with the volume of data or the processing required by SSMS. The report runs if the data is output to a table rather than a chart - so the issue appears to be with rendering the chart.
The chart is rendered when the Category has 200 items with a Series of 150 per Category. The report fails with Category 200 items and Series 200 per Category.
Hi,We have a prod server running on SQL server 2000 64 bit. It is a4cpu server with 16GB of RAM. we have a maxmemory setting of 15.5GBfor sql server. Inspite of 15GB being available for sql server, itstill uses paging file space, a lot. When looking thru task maanger wecan see sql server using 15.5GB of Memory usage and 22GB of Virtualmemory usage. I don't understand why it should even be using closer to7GB of Paging space, when it has so much memory. How does SQl serveruse Virtual memeory vs Physical memory?HAs anyone seen this before.ThanksGG
We have Windows Server 2008R2 installed on VM Server.On that we have three SQL instances running. From few past months we are observing physical memory is going high. Earlier we observed it was at 86-88%, now it is 96-97%.We have 16RAM & 8 CPU cores on VM. what is the best and ideal configuration so that we can rectify the high physical memory issue.
How can I keep my thread alive after an out of memory exception? That is, I understand that sometimes a server may be unable to satisfy a memory request, but I'm okay with waiting -- I'm not okay with being terminated (think of the reaction to Oliver asking for some more). I would think that, in general, when any application makes a request for a resource that is currently unavailble, but may be available at another time, that application (process/thread/fiber) would be put in a Wait Queue for that resource. On a high concurrency system, this could obviously lead to deadlocks; however, I think in the situation I describe below, the killing is overkill.
Discussion & Background:
In my project, I have a SqlFunction, we'll call "SqlDecimal BigFunction()" that will allocate a large chunk of memory (~3MB) and can take anywhere from 20ms to 500ms to complete (on my system, assuming no other processor load). There are also Functions that are used to set control points for BigFunction (implying thread/fiber state -- or, if there is a distinction, Transaction state), which we will call "SqlBoolean SetControlPoint(SqlInt32 x, SqlInt32 y)". The 3MB requirement is constant, regardless of the number of control points. (Incidentally, the actual implementations of these functions are in a referenced assembly)
In low to moderate concurrency (single hyperthreaded CPU with 20 sessions banging it in a loop), it *usually* does okay. In a higher concurrency situation (2 hyperthreaded cpus with 10 sessions stressing this code and 10 other sessions doing regular TSQL Selects) It runs for a long time, but will occasionally throw an out-of-memory exception. (Previously, I was managing my thread state manually with a locked dictionary, an Int32 key, and CreateSession/ReleaseSession calls). When an out of memory exception is thrown while the dictionary is locked, I get an AppDomain unload, which is *completely* unacceptable)
So, I know that sometimes, I won't be able to allocate my 3MB (it could be 3kb, it just shows up more readily with a larger allocation request). That doesn't mean my externalAssembly is "misbehaving" or "off-in-the-weeds". It just means the server is loaded right now and can't satisfy my request. One may catch an OutOfMemory Exception (perhaps to add additional info about the point of failure), but the thread is already being aborted.
I tried modifying this implementation to use a buffer pool that is allocated on start-up. That worked pretty well (reduced % Time in GC a bit, also), but it forced my external assembly to be marked as unsafe rather than just external access because of the Synchronization methods used to manage the buffer pool. It also doesn't scale, at least not as it sits. Its just a fixed size buffer pool. With more processors and less peripheral loading, the extra processors would just be waiting for a buffer. Besides that, I thought there was some escalation policy about "waiting too long", but I may be wrong.
I would like to eliminate the "UNSAFE" attribute from the primary assembly -- mainly because it "sounds scary", but more realistically, because it is unsafe! Or at least, experience in the field points to synchronization issues being a primary cause of unreliability in systems. Also, calling the C# lock, Mutex, Monitor etc call into native code to use the OS for locking. When this happens, SQL doesn't really know what you're waiting for and can't take that info into account when scheduling. All it knows is that you're waiting on an OS lock. I thought the hosting API would've allowed the host to optionally implement its own locking primitives, especially a host that runs its own scheduler.
I've looked into constrained execution regions and Chris Brumme's blog entry on hosting. Using them would help ensure some protection, but I think even they do not protect a thread from being unloaded in the face of an OutOfMemoryException (or any asynch exception); rather, they allow you to safely clean up unmanaged references and ensure state integrity for the appdomain.
At any rate, this is getting a little long winded. If anyone has any feedback, I'd be delighted to hear it.
Thank you.

Good day to all, I'm new here, so I don't know if this is the right forum to post my problem. I have a web application written using C# .net 2005 (W/ajax). The application has a module that uploads data from excel file to the sql server 2005 database. w/c is by the way, i'm using SQL 2005 Express Edition, the app can upload up to more than 10,000 records from an excel file. Everything is ok until it was deployed in a test environment, while having a run through with the system, the application encounter an error after which, we cannot log in to the system anymore. I restarted the server (web and sql server in 1 machine running winxp) then I can log-in again in the system. When I'm tracing where the problem came from, I noticed that the memory usage of sqlservr.exe increases everytime the app connects to the server. I already fix some code to close some objects that might have caused the high memory usage, then I run sp_who in the management studio and there are still connections used by the app AWAITING COMMAND. Then I manually kill (using kill spid) connection that are left opened by the application. But the mem usage of sqlservr did no decrease. Is there a way to release the memory usage of sqlservr.exe? In ASP.Net ? I have a hint that this has been causing the error. Thanks a lot.
