(notice) child pid XXXX exit signal Segmentation fault (11), possible coredump in /etc/apache2

Question

I keep getting the follow error in my Apache log:

[Wed Sep 18 17:59:20 2013] [notice] Apache/2.2.22 (Ubuntu) PHP/5.3.10-1ubuntu3.8 with Suhosin-Patch configured          


        

Answer 1

After an entire day of trying to trace this down, no solutions worked. I eventually however turned Apache to debug level logging and immediately noticed hundreds of notices/warnings with Google's mod_pagespeed for Apache trying to rewrite images from Jetpack's Photon images.

I did a simple a2dismod pagespeed and no more segmentation faults.

Have also noticed my sites are actually running faster now with mod pagespeed turned off.

There seems to be quite a few bug reports about pagespeed causing segmentation faults.

Not sure if its just mod_pagespeed or the combination of mod_pagespeed, wordpress and php .... but turned off now problem gone.

I am done with it for now and also in the process of moving everything to Nginx now. Tracing faults on Apache always turns into a nightmare, with Nginx I can find errors in a few seconds to a minute.
