Yeah. People buying enterprise distros do tend to buy branded RAM
with goodies like ECC from big name suppliers instead of a cheap $20
noname DIMM from "Joe's computers".

So it *could* be a lot of these are crappy hardware, especially
as some of the reports do indicate that the problem went away
when they upgraded their RAM.  Some of the others though, I'm
not so sure.
