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:
I also changed ulimit max open files in the init.d
ulimit -n 60000 -u unlimited
I recompiled the kernel with a modified version
I still can't go beyond 1000 threads. I know this
because I type show processlist in mysql.
What else can I try ?
