[rt-users] Mason killing root httpd2 process

[John Giles]

RT 3.2.2
Mandrake 10.1
Apache 2
FastCGI
MySQL 4

Please help !!

Has anyone else experienced mason killing the root httpd2 process ?
Sometimes the httpd2 crashes and sometimes the box totally locks up
and has to be hard booted.

Anyway, I get this error message in my httpd/error_log when the httpd2
process crashes:
-----------
[Fri Mar 18 00:19:18 2005] [emerg] (35)Resource deadlock avoided: couldn't grab the accept mutex
[Fri Mar 18 00:19:18 2005] [alert] Child 24695 returned a Fatal error...\nApache is exiting!
-----------

When this happens the httpd2 listener crashes and the children continue to
run without a parent.  Killing the children and restarting httpd2 gets RT
back up and running.

Here's a `ps -ef f` output BEFORE the crash:
