如果出现以下错误或错误：

[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

一个报道的解决方案是添加

AcceptMutex flock

到你的主要httpd.conf。

其他报道声称不起作用，并且以下内容会发生变化，所以请参阅哪一种最适合您：

AcceptMutex posixsem
