****************************************************************
Stopping the server (Controller and Servant regions) by issuing
the MVS stop command, for ex. p bbos001, does not close the MQ
connections used by the connection browsers in the Controller
region. After the server is restarted, previous connections
persist and accumulate. This can be seen by issuing the MQSC
command DISPLAY THREAD(*). RRSBATCH type threads show as active
with the ASIDs of previous Controller regions. This also occurs
if the Listener Ports used by the registered MDBs are stopped
and restarted.
Problem conclusion
Close the connection used by the connection browsers when the
server is stopped or if the Listener Port for which there are
connection browsers is stopped.
