DB Engine :: Does Logon Trigger Create Internal Temporary Objects

I create a logon trigger on a sql server 2008 r2 instance,the trigger is very simple,like this:

CREATE TRIGGER tg_login
ON ALL SERVER
FOR LOGON
AS
IF ORIGINAL_LOGIN() IN('sa') AND HOST_NAME()='TestHost1'

[Code] ...

I use master.dbo.LoginRecord  table to record the bad logon. When the trigger is working ,latches produced sometimes,wait type is PAGELATCH_UP  and wait resource is 2:1:3. At this time, a large number of logon failed ,error message is  "Logon failed for login 'login name' due to trigger execution."

I think  logon trigger create internal temporary objects maybe,it is right?
