set swappiness to zero. That will force the machine to use all physical ram before swapping for the most part. Also i have heard that xorg has a memory leak. I do not know if that has been addressed yet and that could be the cause of your issue.

Could you elaborate on that (swappiness) just a bit :-) ? Is this a generic Linux setting, or RH/CentOS specific ? TIA

A memory leak *WOULD* cause this kind of thing. SGI had such a problem a few years back in some version or other of their (released) IRIX OS, & X.org just got back into the game, so that's fairly plausible as well.
