Thank you for the bug report. Please try reducing to the minimum possible the
table_cache=256 i.e: table_cache=32 and test again.
[30 May 2008 13:35] onur ozturk
but i have two ini file and i dont know which one i need to configure first one or second one

and what value i need to get
like;
table_cache=256 to table_cache=128 for first ini
and 
table_cache=32 to table_cache=16 for secont ini
can u explane more pls
[30 May 2008 13:38] MySQL Verification Team
Change the my.ini which the server uses.
[30 May 2008 14:09] onur ozturk
i change my.ini like below
table_cache=32 #it was 256
wait_timeout=460 # there was no wait_timeout descriptin before

now it seems working good
and total ram usage go down from 2.2 GB to 1.8 GB and 
cpu usage is go a little up from %15 to %25

i ll wait and report what will happen

it solve the problem of the man error below

Microsoft OLE DB Provider for ODBC Drivers error '80004005'

[MySQL][ODBC 3.51 Driver]Can't create a new thread (errno 12); if you are not out of
available memory, you can consult the manual for a possible OS-dependent bug

but when i look at error log files and filemon i see two errors still

i see in mydatabase.err ;
080530 15:44:24 [ERROR] C:\Program Files
(x86)\SWsoft\Plesk\Databases\MySQL\bin\mysqld-nt.exe: Deadlock found when trying to get
lock; try restarting transaction
080530 15:44:24 [ERROR] C:\Program Files
(x86)\SWsoft\Plesk\Databases\MySQL\bin\mysqld-nt.exe: Sort aborted

-------------------------------

i see one error in windos filemon;
Request : query information
path : C:\Program Files
(x86)\SWsoft\Plesk\Databases\MySQL\Data\mydatabasename\mytablename.TRG
Result: Not Found

what that two errors mean
thanks

The first error message means you had a deadlock in InnoDB. They are always possible and your application should just expect them and try to repeat same actions later.

The second one means some trigger on your mydatabasename.mytablename table exists but corresponding .TRG file was deleted somehow.
