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.
