-===== What to Do When Apache Runs Out of Semaphores =====
-Taken from [[http://bergie.iki.fi/blog/if-your-apache-ever-runs-out-of-semaphores---/]]
-If you get this error message when trying to start Apache, then you're out of [[http://en.wikipedia.org/wiki/Semaphore_(programming)|semaphores]]:
-# apachectl start
-Ouch! ap_mm_create(1048576, "/var/run/httpd.mm.22903") failed
-Error: MM: mm:core: failed to acquire semaphore (No space left on device): OS: Invalid argument
-/usr/sbin/apachectl start: httpd could not be started
-The easy fix is to just remove all semaphores owned by Apache:
-# /usr/bin/ipcrm sem $(/usr/bin/ipcs -s | grep apache | awk '{print$2}')
-Got the fix from [[http://forums.cacti.net/about675.html|cacti forum]].
