[axxs-sysadmin] apache down due to semaphore issue - FIX

[dave at netaxxs.com.au]

Looked as tho Apache went down, the error in the log was no space left
on device.

Since there is space, looked like an issue with the semaphores, confirmed by :

# ipcs -s

so fixed it with :

# for semid in `ipcs -s | grep apache | cut -f2 -d" "`; do ipcrm -s
$semid; done

then restarted apache.
