Right, but I've always *seen* error messages, dmesg, and, if mcelogd is actually working (I can't figure out why it seems to on some machines, and not on others, or why it doesn't keep running), it's in there. The times we've had lockups, there's been nothing.
That's the frustrating thing.. Not a single error message. It also appears unrelated to system load as I went through 4 hours of the Phoronix test suite that pegged all 8 cores, Unigine Valley benchmark for several loops, memtest.. All passed. But at night it locked up when there was no load.
