It seems like Machine Check Exception: memory controller Read error.
The machine check architecture is a mechanism within a CPU to detect and report hardware issues. When a problem is detected, a machine check exception (MCE) is thrown. If an MCE is thrown and a purple diagnostic screen is displayed, a hardware problem has caused it. There is no other way to generate an MCE. I would recommend you to have a check with hardware vendor and have then a sanity check on the server,
