Hi
Not sure if it is related but we have seen problems before that when you
restart apache very often under load it runs out of semaphore. That
might worth looking into.
To clean up semaphores after stopping apache you can try the following:
ipcs -s | grep www-data | awk '{print $2}'|xargs -n 1 ipcrm sem
PLEASE dont run as is, because it might break things. Purely meant to
get you started.
Regards
