Hi Peter

One of my old HP DL585 had a similar issue but it turned out that the DIMM
slots were at fault. The server chassis had few led blinking red for those
DIMM slots and indicating that they are faulty. I removed the memory from
those slot and re-inserted them to the spare DIMM slots and everything is
working fine since then.
