It can be the other hand round: We once had multiple enterprise class server in a data center that suffered from a strange problem. After a couple of days, sometimes weeks, they stopped working with memory nearly always reported as the culprit. It took some time to find the true reason, which we discovered with the vendor after many hours of analyzing and swapping hardware. The error only occurred when the server was lightly loaded and could be mitigated by disabling the CPU C states entirely in the server configuration. As memory, CPU test or test jobs we had written produced high system load, they never showed any sign of error during test runs because they prevented the CPU from entering higher C states.
