Control-M/Enterprise Manager on a Windows Machine, the Web server keeps going up and down

Alternate Solution prior to version 9.0.21.200:
Option 1. 
The problem is in running wmic.
If the problem re-occurs, run the following command:
wmic process where (name="javaw.exe") get commandline | findstr "emtomcat"

You should see an error , please review the following link to see what may fix the problem:

Option 2.
 Work without the Configuration agent, so it won't kill the Tomcat:
Stop the EM CA from Task Manager -> Services "Control-M/EM Configuration Agent"
You won't be able to have HA or manage all process. But it is a workaround that will let you work, until the wmic problem is resolved.

*** Restating the Control-M/EM Configuration Agent may help **
