Straw-grasping time---does your BE do transcoding or other heavy
lifting?  Have you made sure its CPU heatsink is firmly attached?
I know you tried running memtest; maybe take antistatic precautions
and wiggle your RAM and any other cards in the machine?  Perhaps a
contact has gotten slightly corroded.

(I'd ask, "Is the machine on a UPS?" but it seems unreasonable that
some weirdo voltage sag from the PSU could lead to a BE segfault but
not a machine crash.)
