MYSQL :: Connection To Localhost Lost

Connection Lost
I've got the following problem: I've an select wich gets binary Data out of my sql-table.
The type is longblob and i've lauded some files into it previously with the LOAD_FILE function.

The files have a size between 0.5 and 3MB. I'm loading the data out of the tables with a select like: SELECT data FROM files WHERE file_id=1

After executing the command and some seconds waiting (70 seconds) i get the error "connection lost".

The file i'm actually trying to load has a size of 1,5MB.
(Im using mysql with C++ and the execQuery returns with false after that 70 seconds).

The code above worked fine as long as i use my computer as client use the server in my LAN or the remote server (client and server located in Germany).
When my mate tries to use this code from India the above error occures.

The question now is how can i handle that error? What can i do to get the file even if the inet connection might be a little bit unstable or slow?
Im specially interested in the way how the communication between client and server works. Is the "connection lost" because of instability or because of a timeout?
Every other query works fine from india, only this one which needs some bandwidth is failing.

Besides: i've set the following parameters both for server and client:
mysql_opt_timeout = 5;
mysql_opt_max_allowed_packet = 16*1024L*1024L; //16MB

for the mysql_opt_timeout: is this a timeout which is only important for establishing the connection? or does it affects every query?

Lost Connection
I am getting this error "ERROR 2013: Lost connection to MySQL server
during query" when i try to connect from one client, on all other
clients i don't have any problems connecting to specific server.
Also from this client i can connect to the other servers without any
problem.

Lost Connection Problem
I have problems with the connection to the MySql server. The problem only occure
when running the application on the webserver, never on the local machine.
A strange thing is that it not allways happen, just sometimes. I wounder if the problem depends on a closed connection but then it should appear all the time or ..... ? Code:

Lost Connection To MySQL
Ok heres a quick background on the situation. I run a large mysql orinated website, and tried splitting the load between 2 servers together connected via lan. On server 2 im running debian 3.0 testing/unstable with MySQL 4.0.24. When i try to execute a php mysql search script from Server 1 I get this error:

Warning: mysql_pconnect(): Lost connection to MySQL server during query ..............
Connection Error

I have searched googled, and found a possible solution, which turned out did not work. I simply added these 2 lines to my /etc/hosts.allow

/etc/hosts.allow
mysqld : ALL : ALLOW
mysqld-max : ALL : ALLOW

Also I edited /etc/mysql/my.cnf and added wait_timeout 16000

Insert Into Select - Connection Lost
my problem - want to write a query - find new records in one table and insert in an ohter to generate new keys... See below the statement - but wenn I execute the select part it works fine - as soon as I add the insert into for the select i loose the connection to the mysql server (Error 2013)

Lost Connection To MySQL Server
I am using PHP to invoke mysql_query to my database.
In most cases everything works fine and the query executes perfectly.
Sometimes, I will get a burst of errors and the query will fail with the following error:
Lost connection to MySQL server during query (err_no 2013)

Does anyone know what could cause this?
Could this be a mysql configuration problem, or maybe some network problem?

UNION Causes Lost Connection ERROR 2013
I wrote a for loop to build several select statements that are combined with a UNION. When I execute one of the queries separately, it works, but when I execute
the query with a UNION it returns:

ERROR 2013 (HY000): Lost connection to MySQL server during query

I am able to run additional queries after I get the error, so the connection is not lost. I have tried running the query with the union on MySQL Query Browser and also on the command prompt and I get the same results.

Here is my query:

Lost Connection To MySQL Server During Query
After changing RAM and the ethernet card of my DB server, the problem of getting
frequent:

Database error (error code 102)
Could not connect to database server (Lost connection to MySQL server during query)

Still occurs ;/

I've tried to eliminate all factors (like multiple servers, load-balancers,
replication etc) so I have wrote a php script that only does the following:

- opens db connection
- does a simple select
- closes db connection

If I refresh this page over and over, every 6-7 times I get the above error.
Anyone have any further solutions, ?? I've tried the software (re-installing
mysql, upgrading, etc....) and tried the hardware (RAM, ethernet card). Nothing
seems to help.

The DB server is Linux Redhat 7.3 with the 2.4.18-3smp kernel. I am running
MySQL standard 4.0.13.

Localhost Connection
I am testing on a local machine and am having problems with only ONE query that I try to make and am wondering if there is a fundamental issue I am simply not understanding. This EXACT same code, files,etc. work perfectly on my remote server.

I make my DB query with an include file. The first php script I run queries the DB no problem, but the second simply doesn't. I know that the username, password, localhost etc. is configured correctly, becasue I can log into the DB directly with no problem and because the first query works with no problem. Is there ANYTHING that I am missing? I take the exact same files and dump it onto another server (with a different host name) and there are no problems?! Please help, this issue has been killing me for some time now and I can't even get a testing environment set up to work on.

CREATE INDEX Crashes Server (Lost Connection...)
I'm having trouble with a table I created quite a while ago and now want to add an index to. Here's what I get if I try to add an index on the host field of my table:

mysql> create index Index_host on uselog(host);
ERROR 2013 (HY000): Lost connection to MySQL server during query

Connection was lost because the server crashed. The Windows event log has an event that says "Faulting application mysqld-nt.exe, version 0.0.0.0, faulting module mysqld-nt.exe, version 0.0.0.0, fault address 0x0017dc06."

I've also tried the allegedly identical "ALTER TABLE uselog ADD INDEX Index_host(host)", as well as trying to index a different column, all with the same outcome (server crash).

Thing is, I had no trouble adding an index to the same table a week or so ago. The table was smaller then (and had only one index), but even now, it's not very big by DB standards, so I can't imagine that's the problem.

(My table had ~900K rows earlier today, which I pruned down to 140K rows after my first failed attempt to add the index. Puny! Only 55MB data length, according to MySQL administrator.)

ERROR 2013: Lost Connection To MySQL Server During Query
I have recently installed suse 9.0 linux which has MySQL 4.0.15 as part
of the distribution. After I set up my users I was able to use
mysqldump and pipe it into mysql on my windows machine running 4.0.16 to
dump a database to the linux box. However, now when I try to login to
the linux box from another machine on the network I get a query timed

I have MySQL 4.1.10 running successfully on an office XP machine, but
when I try to set up similar XP box at home I continually get this
error: "Error 2013: Lost connection to MySQL server during query".
The install went fine, and Windows XP is recognizing it as a running
service. But whenever I try to connect via one of my GUI applications
(e.g., MySQLFront), the error appears.

I have scoured this forum and Google looking for this error, but
haven't found anything helpful so far. This post ...

my service does not stop when I hit the error.

I've lost a couple days to this problem, and I've uninstalled and
reinstalled the app several times. I don't know where to go next. I
need to have 4.1 running because we need the Unions and Subqueries.

Network Problem - ERROR 2013 (HY000): Lost Connection ....
I'm having problems with my MySQL server when I do queries that return a lot of data over the network.

It's fine if I connect via the local UNIX socket

> mysql -u root -p

> SELECT * FROM users limit 100;
returns 100 rows in a few seconds

>SELECT * FROM users limit 1000;
returns 1000 rows in a few seconds

But when I try the same thing but connecting to the network port I get

If I watch the traffic with tcpdump it sends a few packets right at the start and then doesn't appear to be sending anything for the next 15 minutes until the error appears.

I'm using 5.0.27-standard-log community edition.

I get this message instantly (< 1 second) when I try to connect to the MySQL server from a remote host. I am using "mysql" at the remote client. Does not matter where the remote client is: on Solaris, on RH 7.2, on Fedora. Same thing every time.

I am using the the mysqld as it comes out of the box on Red Hat Linux 8.0.

I tried a google search on Error 2013, and there are a lot of responses:

Can't Establish Connection To Localhost With MySQL Server
I recently installed MySQL server on my PC, for the primary purpose of converting MS Excel files to core SQL (using another conversion program to access the server interface)...

In my conversion application, I am unable to establish a connection with "localhost"....

I tried going into the MySQL command line client, but I can't get past the initial password prompt...FYI, I didn't enter a username and password during installation because I didn't want that.....

Anyway, all I really want to do is convert Excel files periodically...Does anyone have any ideas on what I need to do to accomplish this?

Also, my conversion application is a trial version and expires in a few days...Does anyone know of any good, FREE conversion applications?

SQL Execution Error # 2013. Response From Database: Lost Connection To MySQL Server
I'm upgrading to v4.1 from v3.2 on a Windows XP box; I did an uninstall on the previous version, but Windows services did not remove it as a service (v4.1 was logged as a new service, MySQL4).

I breezed through the install process, but I get an error when I try to launch the .exe file from the command line. It says ... "ERROR 2013 (HY000): Lost connection to MySQL server during query." MySQL4 is now an automatically started service under Windows and mysqld-nt is operating in the Task Manager as a process.

When I try to connect via MySQLFront, I get the following error message: "SQL execution error # 2013. Response from database: Lost connection to MySQL server during query."

User-defined Function: ERROR 2013 (HY000): Lost Connection To MySQL Server During Query
With mysql-4.1.1-alpha, using any User Defined Function ( UDF) at the
query execution stage, on Linux 2.6, gave me the following error:

"ERROR 2013 (HY000): Lost connection to MySQL server during query"

However, upgrading to mysql-4.1.2-alpha seemed to solve the problem.

Both versions were configured exactly as follows

../configure --with-openssl --enable-thread-safe-client --with-mysqld-ldflags
=-rdynamic

The only way I could solve this was by upgrading to 4.1.2-alpha-log. Then,
recompiling the functions, drop the old UDF functions, then, recreate.
So far so good.

Anyway, if you run into this problem, or just want more detail on the sample
User Defined Functions that come with MySQL ( /sql/udf_example.cc), I've put
my notes in the following link ( TIP 27 )

Lost Connection To MySQL Server During Query Socket Error On Read. WSAGetLastError Return 10054($2746)
We just migrated our MySQL database from a NetWare server running version 5.0.21 to a openSUSE box running version 5.0.45.

Everything ran fine for a couple of days, then clients began losing their connections and creating new ones without the old threads being terminated. This behavior is the same for the Delphi client we use to access our database as well as the MySQL Administrator tool.

I've tried adjusting connection_timeout, but overall the settings for this server are the same as the previous one that ran without issues for a year.

Encountering 2013 Error ("Lost Connection To MySQL Server...")
I have a nightly job that performs backups on my MySQL servers. There are three production MySQL instances on different machines. My backups have been running successfully for months (until now).

However, on last night's backups for one instance, a couple of database/schemas (appear to have) backed up successfully, but the larger schemas failed, as follows:

=======================================
Backup of schema dhunt was successful in 0 seconds
Backup of schema mysql was successful in 0 seconds
Backup of schema support_appl was successful in 0 seconds
Error: Backup of schema support_dict was not successful (1115 seconds):
mysqldump: Got error: 2013: Lost connection to MySQL server during query when retrieving data from server
Error: Backup of schema test was not successful (0 seconds):
mysqldump: Got error: 2002: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) when trying to connect
=======================================

I re-ran the backup cron job with the same results. Does anyone have any troubleshooting suggestions?

Control Center "lost Connection..." And ByteFX
I'm currently trying to move from MS SQLServer to MySQL, running on
windows XP.

When trying to connect to mysql on localhost with mysql control center
I get the 2013-error "Lost connection to MySQL server during query".

I can connect from command line. If I do so, and change passwords by
using OLD_PASSWORD('<password>'), control center runs nicely, but then
ByteFX fails to connect with "Access denied for user...".

If I set the passwords with PASSWORD('<password>'), ByteFX runs
nicely, but Control Center fails.

Lost Connection To MySQL Server During Query / Server Has Gone Away
All of a sudden the server stopped working. When trying to execute a simple INSERT both from PHP and Query Browser, the server crashes and I get either "Lost connection to MySQL server during query" or "Server has gone away" errors.

The problem started on 5.0.18, and upgrading to 5.0.41 didn't help. I'm using Windows XP SP2.

I've seen quite a few posts on similar problems, but no real solutions though. Is that a bug?

Changes Made In One Connection Does Not Reveal In Another Connection At Once.
I use many connection and the same as many threads in my server app to gain performance on a multicpu machine.

Firstlly i call "set autocommit=0" and wrap every statements with "start transaction " and "commit". i use mysql_stmt_execute for every statement rather than mysql_real_execute except those that can't be prepared. The version of mysql is 4.1.11 under Debian linux.

In one connection of one THREAD i insert a row into a table. After i got the sucess code and the last insert id, i then do a "select" from another connection in another THREAD with the "last insert id" return by the previous insert . I expect the select can fetch the row that i have just insert , but some time it does and some time it doesn't.

is there any funtion like "mysql_....flush...cache.." to make the changes from one connection to be reveal to the global at once?

Lost. <_>
I am currently learning PHP, and know a bit of it so far. Currently I am using a login system that checks for a file named what the person typed for the username, and then checks inside the file for the password. I really need to know how to use a MySQL database.

Can someone explain this really slow to me? Every site goes through it really fast not explaining all the details. And could you help me figure out how to make a login system?
