The solution to my above system locking up was to disable the on-board bge NIC via the BIOS, and plug in a dual intel NIC that uses the em driver. Also, ensure you have at least a Rev C board; mine is a Rev E. Stable 10 days now under same load that would cause network failures and potential system lockups daily. I have no idea if this is due to the driver for bge being buggy, or if plugging in the intel NIC changed some electrical properties of the system to stabilize it. Hope this note helps someone else save a *lot* of time figuring it out. Vivek Khera, Ph.D. +1-301-869-4449 x806 --Apple-Mail-27--5179914--
