Virtual SBS2011 crashes every half hour with EventID 41 (63)
Posted on 2013-12-13
I have a customer with a very strange problem with their Small Business Server 2011.
This server runs as a virtual server on a 2008R2 Server with HYPER-V.
The SBS crashes about every second hour around the clock without no visible reason.
I have been checking the physical host server for logged events, there is none, plus possible reasons like power failures or local hardware problems.
If I check the SBS's Event Viewer, it tells me that I have about 50 critical events in the last 24 hours. 2 is some Sharepoint stuff which I dont believe is important BUT 48 is EventID 41 "Kernel-Power", task category (63) which says:
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
There are no other description what so ever!
Can anyone give me a hint?
