  * PROBLEM DESCRIPTION: If the associated cluster transmission  *
  *                      queue to an expired channel has been    *
  *                      deleted by the user then a S378 abend   *
  *                      in the Channel Initiator can be issued  *
  *                      during cluster maintenance.             *
  ****************************************************************
  The user deleted a locally defined queue that was previously
  associated as the transmission queue for a local cluster sender
  channel. When that channel was not used for a long time (over 90
  days) then, via internal automated processing in the queue
  manager's cluster repository manager, the local auto-defined
  channel definitions for it were expired from the local cluster
  cache. At this time the queue manager was calling MQOPEN on the
  cluster transmission queue that was configured for that channel.
  If the user had deleted the queue, then this failed, and in the
  error-handling logic that follows, the CHINIT can issue a S378
  abend.
  

Problem conclusion

• The MQ product code has been altered so that the missing
  transmission queue is not treated as an error condition at this
  point in the processing.  The cluster repository manager
  completes its removal of the old records from its cache without
  any errors.
