Apache Restarting Nightly

[orty]

Every night or two, I get an email roughly like so:

SUBJ:httpd on myserver.net status: failed
MSG:httpd failed @ Tue Mar  6 01:46:17 2012. A restart was attempted automagically.

Service Check Method:  [socket connect]

Reason: Timeout while trying to connect to service: Died at /usr/local/cpanel/Cpanel/TailWatch/ChkServd.pm line 561.


Number of Restart Attempts: 1

Apache comes backup just fine, but I'd like to figure out why it's dying in the first place.

Looking at the Apache Error logs, I'm seeing this around that time:

Any ideas or other places I should look?

At the bottom of this thread you've started, several Similar Threads, like this one might be useful to you:
Why is apache restarting every two hours?

Oooh...piped logs. Must have missed that in the change logs. I'll give that a whirl and see if that helps. That was the only thing I didn't already have checked (as my logs are all rotating properly, so nothing's getting too large).

Thanks!
