the SBS 2011 server with 2 Raid 1 (mirrored) volumes of 146 GB and 300 GB , 24 GB Ram, and 8 Core CPU at 2,4 GHZ is getting stuck from time to time with having CPU0 at 100%.
When looking into the task manager or resource monitor I can see that CPU0 gets at 100% but there is no service, task or programm visible causing it.
Volume Shadow Service is active on both volumes. Could it be related to this?
The harddrive only show some peaks but are not running permanently at 100%. It is likely 30% or less.
The event log shows a VSS-error "1376" with event id 8230 from source VSS that spearch could not be resolved. Registrykey VssAccessControl should be reviewed.
Some sources state that this error can be ignored as it is not really an issue.
Can someone please point me to the right direction?
