I have 3 domain controllers that are all running between 85-95% CPU usage. This issue started over the weekend and nothing is showing up in the logs. I've used process explorer to narrow the issue to the system service. I would also like to note, this has not affected performance or availability of any services, critical or otherwise.
Details and what I've ruled out...
Two of the DC's are Server 03 and the third is 08.
The 03 servers use Symantec and the 08 uses Mcafee.
All 3 are virtualized on 3 different hosts using VMWare.
Due to the fact that they're different OS's and they have different AV's running, I do not think it has anything to do with AV. I've also run scans to check for viruses and turned up nothing.
When I look at the threads of the process, the culprit appears to be "srv.sys+0x1a602 "
Google hasn't turned up much beyond some Microsoft hotfixes revolving around AV patches, which I am inherently skeptical of.
Any ideas would be great! Thanks!
