  ****************************************************************
  When a Requester-Server channel connects to MQ via the
  INDISP(GROUP) shared listener, but the SERVER channel definition
  uses a private non-shared transmission queue, an erroneous
  record may be created in the shared channel status table.
  
  This record may cause other queue managers in the QSG to issue
  an internal START CHANNEL command. When this START CHANNEL
  is processed by the channel initiator that already has the
  channel active, then message CSQX477E may be repeatedly issued.
