Error description

  • After upgrade to MQ v8, Partial Repository's cluster sender
    channels occasionally get stuck in status INITIALIZING and do
    not transition to RUNNING.
    
    Ending and restarting the channel results in initializing again.
    
    Manager's log will show AMQ9514 Channel in use.
    
    Full repositories can experience this problem also.
    

Local fix

  • End and restart the Queue Manager. Consider changing the
    channel inactivity timeout to 0 to avoid after restart.
