  apache claims 'no space on device'

keywords : apache ipcs semaphore no space on device lock accept

tested with apache 2.0.43 and 2.0.45

When dealing with mem-leaks in my mod_perl-apps I ran into a curious apache-problem. After a while apache could not be started but failed with strange errors like:

[emerg] (28)No space left on device: Couldn't create accept lock

or
[crit] (28)No space left on device: mod_rewrite: could not create rewrite_log_lock Configuration Failed


There was definitely enough space on the device where the locks are stored (default /usr/local/apache2/logs/). I tried to explicetely different Lockfiles using the LockFile-directive but this did not help. I also tried a non-default AcceptMutex (flock) which then solved the acceptlock-issue and ended in the rewrite_log_lock-issue.

Only reboot of the system helped out of my crisis.


Solution: There were myriads of semaphore-arrays left, owned by my apache-user.

ipcs -s | grep nobody

Removing this semaphores immediately solved the problem.

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