Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects all users of the WebSphere MQ Version 7
  Resource Adapter.
  
  Platforms affected:
  All Distributed (iSeries, all Unix and Windows) +Java
  ****************************************************************
  PROBLEM SUMMARY:
  WebSphere Application Server Version 7 uses the WebSphere MQ
  Version 7 Resource Adapter to manage connections to a queue
  manager.
  
  If a problem occurred removing a connection from the pool of
  connections maintained by the Resource Adapter, it was possible
  for the pool to end up in an inconsistent state. This resulted
  in the error reported in this APAR.
  

Problem conclusion

• The WebSphere MQ Version 7 Resource Adapter connection pool
  logic has been rewritten, and now correctly handles the
  situation where an error occurs trying to remove a connection.
