I didn't go into detail in the article, but the server in question is running a Supermicro X10SLH-F-O motherboard, ECC RAM, and a Haswell CPU, in a Rosewill RSV-L4411 4U chassis. Is there a hardware problem here? For sure. But you can't write this off as being some dusty overclock mess bought at someone's garage sale.

I have, incidentally, seen this in corporate environments on traditionally-engineered sever-class hardware as well. This is just a much more easily-discussed case.
