I had one a few years ago where it took about 3 days for memtest to
catch the bad RAM but even after fixing that there were random
crashes.  Turned out that the bad RAM had caused some disk corruption
which was partly hidden by raid1 mirroring.  Once in a while a program
block read would hit the bad copy, but when you look for it everything
looks OK...
