Error Message :
When a CP crashes, users that are connected to that CP appear as a “ghost user”.
This user will appear as duplicate user in the Connections section of the Automic Web Interface (AWI) or System Overview's Users section in the Java Client.
These user connections are persistent and count as another connection on licenses.
Root Cause: This is a bug where user sessions are not released after a CP crashes.
