As I mentioned in the description the host is equipped with ECC memory. dmesg didn't show any sign of memory error that
I would expect from a bit flip inside RAM.
The hardware is
* ASRock Rack C226 WS mainboard
* Intel Xeon E3-1245 v3
* 4x Kingston 9965525-055.A00LF 8GB ECC memory.
Also the host has been running fine after the bug triggered for 1.5h and today again for 7h.
