[ppc1]

My apache went down and watchguard did not start it back up again..I have no idea what these errors mean, and i have searched high and low for an anwser:

[Thu Aug 17 18:56:49 2006] [emerg] (22)Invalid argument: couldn't release the accept mutex
[Thu Aug 17 18:56:49 2006] [alert] Child 6067 returned a Fatal error...\nApache is exiting!

Any help is appreciated....

thanks

Did you check Google?

Seems like many things could trigger it, depending on the mods you have enabled - you should watch your error logs around the time this is happening...
