Great work digging into this issue. A memory test is probably in order. I learned about ECC RAM when I was trying to figure out why server lease deals were so inexpensive relative to others. For instance, the last I checked, hetzner.de's hardware does not support ECC RAM. I am of course not calling out hetzner, and there are other factors in such deals.
