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.

Having a lot of available memory is different than having too few stack space reserved. Running through the webserver a php script of <?php passthru('ulimit -a');
may help determine the used stack size amount.
If you got a core of those processes, that could also help determining what produced the segfault.
