Memtest didn't show any errors, but between Frank, early in the thread, saying that he had found memory errors that memtest didn't catch, and remove of DIMMs apparently fixing the problem, I too soon jumped to the conclusion it was the memory. Certainly there are other explanations. I see that

Looks like it was RAM. I ran memtest+ 4.00, and it found no problems. I removed 2 of the 3 sticks of RAM, ran a backup, and had no errors. I'm running more extensive tests, but it looks like that was it. A new motherboard, CPU and ECC RAM are on the way to me now. -- This message posted from op

Yeah, this morning I concluded I really should be running ECC ram. I sometimes wonder why people people don't run ECC ram more frequently. I remember a decade ago, when ram was much, much less dense, people fretted about alpha particles randomly flipping bits, but that seems to have died down.
