Java.exe running high CPU

[Daffy25]

I am running CA 12.03 with a distributed windows server environment on virtual machines. It seems once users start using the system the java process is over 70 and even into the 90s for CPU utilization. Memory usage is between 30 and 40 percent. Once the number of users drop down under 10 the java.exe for the dispatchers doesn't drop down. If I change the active Content Manager to a secondary content manager the java processes on the dispatchers drops below 10% and will increase over an hour or so. Also, if I stop one of the two dispatchers this will clear the processing. I do not have any scheduled jobs or DQM in use. My logging is minimal or basic and the logging ports are unique. The reports that do run on demand are quick lees than a minute. I have also confirmed my virus software is not scanning the Cognos folders.

Has anyone seen this behavior before? Maybe a setup with my VM? Any suggestions welcome.
