WebSphere MQ V7.0 Fix Pack 7.0.1.5
WebSphere MQ V7.0.1 for i5/OS Fix Pack 7.0.1.5

APAR status

• Closed as program error.

Error description

• The message which is in transit is getting lost when a WebSphere
  MQ XMS .NET V2.0 CLIENT application is closing the session,
  consumer or connection. This happens only for non-persistent
  non-transacted sessions.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of XMS .NET applications which run as synchronous
  consumers operating with non-persistent and non transacted
  messages in Managed connection mode.
  
  Platforms affected:
  Windows
  
  ****************************************************************
  PROBLEM SUMMARY:
  The Session, Consumer or Connection close method was not
  waiting for the asynchronous message delivery thread to complete
  the operation. This was causing the main thread to close before
  completing the consumption of messages which are available in
  client side.
  

Problem conclusion

• An appropriate locking mechanism is introduced to wait for the
  asynchronous delivery thread to complete the message processing
  before closing the Session, Consumer or Connection.
