Error log of apache : mod_rewrite: could not create rewrite_log_lock [crit] (28)No space left on device: mod_rewrite: could not create rewrite_log_lock Configuration Failed

===========
Reason For The Error---> Checking your disk shows that you have plenty of space. The problem is that apache didn't shut down properly, and it's left myriads of semaphore-arrays left, owned by my apache-user.


Fix--> Run The Command in shell
ipcs -s | grep nobody
Removing these semaphores immediately should solve the problem and allow apache to start.

ipcs -s | grep nobody | perl -e 'while (<STDIN>) { @a=split(/\s+/); print `ipcrm sem $a[1]`}'
