apache semaphores

Hi,

I have a busy wordpress website

For unknown reasons the apache semaphores get full like each 1-2 days, sometimes each 6 hours and apache dies and I can't restart it until I clean the semaphores with the following command:

Code:

ipcs|grep apache|grep 0x|awk '{print $2;}'|while read a; do ipcrm -s $a;ipcrm shm $a; done

Can someone please explain me what are these semaphores and how can I determine why they are getting full?

How do I stop them from getting full?

Thanks in advance

Semaphores can be created by other programs other than apache. The user shown in ipcs is not always the creator.

For apache try using...

AcceptMutex flock

...so apache doesn't use semaphores.
