Thanks for breaking that down. No I'm not all that familiar with swap details so it helps to have some insight. The box flatlined around 3am on Monday morning and memused (sar) was around 96%. All the swap space was untouched. Maybe every process running was active, and unable to be swapped, so the box just up and died when a request came in to allocate more ram. I just don't have enough of an understanding of swap to say that was what happened. I do remember a day when you could heat a small room with the swap activity generated on earlier 2.x kernels, but things seem much different with 2.6.
It could be hardware related. Maybe the hardware doesn't like that memory module, or it has problems. Did you memtest+ all your memory?
