We have 8 hosts and about 50 servers for various functions between them. The past 2 days random ones on different hosts will show an alarm Virtual Machine CPU usage. Most of the times the servers were too stalled to login to and had to be powered off and back on and then they are fine. After getting into them I cannot find anything in the logs to suggest the cause. Its happened to 5 separate non related servers in the past few days. Is there a VMware related common problem I am missing?
