Hmm... Well, I'm using the exact same setup as on the 2x2.2GHz Xeon
with a 4x700MHz Xeon system with 2GB of memory where I've not seen
this behaviour. The 4x700MHz system runs 3.1_STABLE, though, and it
appears to occasionally have issues with process run-down (causing
either panics or kernel page faults), ref. PR #35150.

OK. Maybe I should test with that program as well. However,
the name service for mersenne.org appears to be inoperational at
the moment -- ns1.sbsi-net.com doesn't respond, and ns2.* replies
with SERVFAIL. Bah!
