I have mysql-server 3.23.49-8.9 in a debian woody, chosen for its stability. It looks like the server stops accepting connections when it has created more than 1024 threads.
The kernel is 2.4.29.
failed: Can't create a new thread (errno 11). If you are not out of available memory.
I have searched a lot for OS problem :
I changed kernel thread max: more /proc/sys/kernel/threads-max 14336
I also changed ulimit max open files in the init.d mysql script:
ulimit -n 60000 -u unlimited
I recompiled the kernel with a modified version of limits.h
I still can't go beyond 1000 threads. I know this because I type show processlist in mysql.
What else can I try ?
