[emerg] (13)Permission denied: couldn't grab the accept mutex
If you get the following error, or errors:
[Wed Nov 16 08:37:07 2011] [emerg] (13)Permission denied: couldn't grab the accept mutex
[Wed Nov 16 08:37:08 2011] [alert] Child 5376 returned a Fatal error... Apache is exiting!
[Wed Nov 16 08:37:08 2011] [emerg] (43)Identifier removed: couldn't grab the accept mutex
[Wed Nov 16 08:37:09 2011] [emerg] (22)Invalid argument: couldn't release the accept mutex
[Wed Nov 16 08:37:11 2011] [emerg] (22)Invalid argument: couldn't grab the accept mutex
one reported solution is to add
AcceptMutex flock
to your main httpd.conf.
Other reports claim that doesn't work, and that the following does, so see which works best for you:
AcceptMutex posixsem
With apache 2.4, use
Mutex instead of
AcceptMutex
Note that when adding customizations to the main httpd.conf, you'll need to use
one of the two methods to prevent your settings from being lost.
