  Several of the following messages are received during
  startup/shutdown of the CICS/WMQ adapter:
  DFHMQ0480 E MQCC=2 MQRC=2195 QRPL at X'000A0000' FRB at
  X'000A0000'.
  This is because the TCB which was allocated during initial
  CICS/WMQ connection processing, to call the WMQ address space
  to determine the release of WMQ being used, has subsequently
  been allocated to a long running non-WMQ related task, causing
  the disconnect logic to incorrectly assume there is still a
  WMQ task in the system.
  

Problem conclusion

• DFHMQCON has been altered so that the TCB, allocated during
  initial CICS/WMQ connection processing, to call the WMQ address
  space to determine the release of WMQ being used, is deleted
  immediately after use.
