Current servers (R710s) use DDR3 - Synchronous Registered (Buffered) ECC memory.
We don't think there's anything wrong with the hardware, as the
problem has persisted across various physical servers (the R710s
replaced 2950s). We also don't have any other intermittent issues
(postgres crashes, application server crashes, etc) that would
indicate random bit errors.
