It only affects mediawiki, the other areas on the server have no issues, e.g. forum, task-management system.. as it is quad core machine with 16GB of RAM I'd be somewhat amazed if it were sufferering. It flat lines at 0% cpu usage and we have still to exceed 1GB of RAM used. I have installed moinmoin onto the server, which is supposedly a heavier system and it runs perfectly. So, I'm at a complete loss as to what is causing access to the mediawiki index page to cause the seg-fault.
If all else fails then strace. But really, there should be some relevant log messages. Maybe you're looking in the wrong place or don't have enough logging enabled. See https://www.mediawiki.org/wiki/Manual:How_to_debug
