We don't know. The checksum mechanism is designed to catch hardware
problems. So one must certainly consider that as a likely cause. If it
is instead a software bug then it should be reproducible. Are you
seeing any consistent patterns? If not, then I'd lean towards hardware.
Michael Stack has some experience tracking down problems with flaky
memory. Michael, did you use a test program to validate the memory on a
node?
Again, do your nodes have ECC memory?
Sorry, I was checking on that. No, the nodes don't have ECC memory. I
just priced it out and it is only $20 more per Gig to go ECC so I think
that is what we are going to do. We are going to do some tests and I
will keep the list updated on the progress. Thanks for your help.
