Hello,
I get a lot of "AH00051: child pid 16774 exit signal Segmentation fault (11), possible coredump in /usr/apache2/2.4".
Trying to pin point the problem but not sure the best way to go about it, since it does not look like a single PHP page does it, but could be within the PHP code of the website or mediawiki sites.
