Pretty sure, all boxes have ECC memory and mcelog has not reported
anything on the nodes in question right now - we usually have only a few
spurious MCE errors a week. We have encountered 17 of these incidences
within the past week and basically nothing before - I don't think that
memory in 17 nodes goes bad just by upgrading the kernel or out of
coincidence.

I'll pick 4-5 nodes for memtests just to be sure.

Cheers

Carsten
