fix apache - no space left on device: couldn't create accept lock or cannot create sslmutex
the answer you entered to the math problem is incorrect.

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
or
[wed dec 07 00:00:09 2005] [error] (28)no space left on device: cannot create sslmutex
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 apache
removing this semaphores immediately solved the problem.
ipcs -s | grep apache | perl -e 'while (<stdin>) { @a=split(/\s+/); print `ipcrm sem $a[1]`}'
system

thanks for your help
the following is doing the same if you don't want to use perl:
ipcs -s | grep apache | gawk '{ print $2 }' | xargs -n 1 ipcrm sem

great. you saved my live!!! (rebooting was not an option for me).
just my two cents. next the equivalent with bash+textutils instead of perl (yes, i don't like perl, it's so ugly to read):
for ipsemid in $(ipcs -s | grep apache | cut -f 2 -d ' '); do ipcrm $ipsemid; done
have a nice day

fix apache - no space left on device: couldn't create accept loc
killing the semaphores is a nice temporary solution to this problem, but i have been dealing with it for months and i was wondering if there is a more permanent solution to the problem of memory leaks here?

correction
very helpful information, but the command line to fix the problem is not correct. the while() shold actually be while(<stdin>). so cut-and-paste this line:
ipcs -s | grep apache | perl -e 'while (<stdin>) { @a=split(/\s+/); print `ipcrm sem $a[1]`}'
