I checked this and yes it does seem to happen whenever apache kills a  
process, however in my case, I don't know why it is killing so many  
processes.

How do I remove the semaphores with ipcrm. If I do:

# ipcs -s
IPC status from <running system> as of Mon Jan  7 10:14:53 2013

Semaphores:
T        ID     KEY        MODE       OWNER    GROUP
s    196608          0 --rw-------  webuser webgroup

There is only one listed. Then if I removed it with:

ipcrm -s 196608

Apache stops. Even if I restart it, then it doesn't do anything. I  
never see any new semaphores. The only option I have left is to reboot.

Thanks,
Al
