Comment 14 for bug 1159748

I'm glad I stumbled onto this bug. My full information is available at http://stackoverflow.com/questions/16304844/php-apc-causing-apache-to-seg-fault.

- I am not using RequestTracker.

- This happens for me any time I issue "sudo service apache2 graceful". Issuing reload doesn't seem to cause mine to sigfault, but graceful does.

- Apache reliably goes down around 6:45am every day, which, as another poster noted, is when logrotate is set to run. In my logrotate scripts, I restart apache2 gracefully.

- When apache2 segfaults, I get the following error in /var/log/apache2/error.log:

[Tue Apr 30 11:05:33 2013] [notice] Graceful restart requested, doing restart
PHP Fatal error: PHP Startup: apc_mmap: mmap failed: in Unknown on line 0
[Tue Apr 30 11:05:34 2013] [notice] seg fault or similar nasty error detected in the parent process

Does anyone have any clue as to what's going on here?
