Error Message :
After performing a Zero Downtime Upgrade (ZDU), several users are shown in the System Overview as connected to a CP of the old MQSET, even though this CP is no longer running. These connections cannot be disconnected in any way. Even a restart or cold-start of the system does not solve the situation.
However, it has no negative impact on normal system operation.
Root Cause: A user could not be disconnected from an old CP, which is no longer running and nor connected to the Automation Engine.
Update to a fix version listed below or a newer version if available.
