If that was the case, then it would be repeatable. And if it was a
fairly quiescent system that hung because of software trouble, then
there are few interacting processes to look at.

If there were only two things going on at night (seti@home and the
periodic scripts) _and_ they've both been through the same stuff on a
regular basis without a crash (and they don't interact, which they seem
not to) then the evidence leans towards your conclusion (it's a
software problem) being doubtful; this isn't cargo-cult stuff - the
software in question is not mysterious, it's pretty transparent.
