We have a Windows 2012 server with an Intel Xeon E5-2430L v2 @ 2.4GHz and 32GB of RAM. One of our other servers died so I setup Oracle VM and created a virtual machine out of our backup (from Shadowprotect). The virtual machine is running Windows Server 2003 Enterprise Edition.
The virtual machine will run GREAT for about a week (haven't had enough time to figure out if there is any consistency) then it will all of a sudden be using 100% of its own resources and I can never get it to stop. The last time this happened I created a clone and then ran that and it worked for about a week.
I have Process Explorer installed but I don't see one process stealing all the CPU usage.
I will attach a screen shot once it comes back up - been waiting 20 minutes now.
