Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users using MQ applications which often connection to and
  disconnect from the queue manager.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  A defect in managing connection data during MQDISC from
  applications could result in multiple attempts to clean up and
  internal structure related to a connection, if the application
  was in the process of disconnecting when the QM was ending. The
  second attempt to clean up the data structure generated the FDC
  record, as the structure was not found, but there was no
  functional consequence of this error.
  

Problem conclusion

• The MQ queue manager channel code has been modified to resolve
  the problem in cleaning up the connection data.
