I've seen a machine where it took 3+ days of running memtest86 to
catch the error. And then after replacing the RAM, the machine still
crashed occasionally. Turned out the software RAID1 mirrors had
mismatching contents caused by the bad RAM and even though it would
check clean, sometimes the read would come from the other mirror.
After fixing that, the server has run for years.
But in general, I always suspect power supplies first for mysterious crashes.
