It only affects mediawiki, the other areas on the

e.g. forum, task-management system.. as it is quad core machine with 16GB

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
