  The Change Team can see the cause of the problem.
  InquireChannelNames creates a permanent dynamic queue using
  QMODEL SYSTEM.COMMAND.REPLY.MODEL. However when it closes the
  queue it does not specify MQCO_DELETE, so the permanent dynamic
  queue remains indefinitely.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of WebSphere MQ Version 8          *
  *                 Release 0 Modification 0.                    *
  ****************************************************************
  * PROBLEM DESCRIPTION: Each time the CHINIT address space is   *
  *                      started a new permanent dynamic queue   *
  *                      is created, but does not get deleted,   *
  *                      leading to an accumulation of queues.   *
  *                      This will be seen by issuing command:   *
  *                      DISPLAY QLOCAL(SYSTEM.COMMAND.REPLY.*). *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When the CHINIT is started the function InquireChannelNames
  creates a new permanent dynamic queue using the QMODEL
  SYSTEM.COMMAND.REPLY.MODEL. The queue is then closed with
  option MQCO_NONE and thus does not get deleted. On each CHINIT
  restart the number of these queues increments by one.
  

Problem conclusion

• The MQCLOSE option for permanent dynamic queues created by
  InquireChannelNames has been changed to MQCO_DELETE_PURGE
  so that the queues are deleted after use.
