I am experiencing an strange issue in which a resident VM seems to be crashing the whole host at least once a day. This VM is the only VM on any host at any given time. The symptoms are, the VM will become unresponsive, then eventually the host will as well. If you issue a restart command to the host from Vcenter, nothing happens. If you do the same from the console in front of the physical host, it still does not restart. I have to force shut down the computer. This behavior continues to occur when I move the VM to another host and data store.
This VM was working fine for the longest time, but it now starting to have these issues.
Any ideas as to what maybe causing this behavior or where to start looking?
