Local fix

• MQRC_Q_MGR_NOT_AVAILABLE (2059) WHEN ASYNC CONSUME APPLICATION
  ATTEMPS ISSUES MQDISC AFTER QUEUE MANAGER END
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of WebSphere MQ V7 Asynchronous Consume functionality
  
  Platforms affected:
  All Distributed (iSeries, all Unix and Windows)
  ****************************************************************
  PROBLEM SUMMARY:
  When an asynchronous consume application is called back to
  indicate that unavailability of asynchronous consume function
  (possibly due to the queue manager having ended), if the
  application performs an MQDISC in an attempt to clean up
  resources, there is lacking toleration that the aysnc consume
  thread may have already performed the common cleanup operations.
  

Problem conclusion

• The problem has been fixed by accepting the queue manager may
  have already ended and enabling the resources on the
  application thread to clean up the remainder of the connection
  information.
