Error description

  • The problem starts with the  CWSID0019I: Configuration reload,
    triggered by a BPM config change.
    
    This causes the SIBus to recreate several queues and move any
    existing messages from the old version of the queue to the new
    one.
    
    In this case there is an MQLink running actively putting
    messages on one of the queues. While doing this it discovers
    that the version of the queue it started putting the new
    message on to has disappeared, causing the issue.
    
    The messages themselves may be put on the exception
    destination, which can be checked for any expected messages.
