Yeah, I was thinking it sounded like a hardware problem too.
The box was previously up and running fine; I asked if there were recent
power hits or anything like that. (Due to faulty electrical wiring in
our house, we went through two power supplies and a motherboard
recently, and that was right through a surge protector.)
"Uncorrectable ECC error" basically means that the memory failed
its auto-correct, doesn't it? So I'd bet on the RAM also.
Googling yields:

as a kind-of-interesting thing.
Cheers,
