IV27277: AMQRMPPA MEMORY LEAK WHEN AN ERROR OCCURS ON ACCEPTING A REMOTE CONNECTION

WebSphere MQ V7.5 Fix Pack 7.5.0.2
Fix Pack 7.1.0.3 for WebSphere MQ V7.1
WebSphere MQ v7.5.0.2 Hypervisor for RHEL

APAR status

• Closed as program error.

Error description

• When a remote connection request fails during the binding phase
  the memory allocated to accept the session is not freed
  correctly, resulting in, over time, a potential build up of
  memory usage in the amqrmppa process.
  

Local fix

• Local Fix￘
  none
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users with long running amqrmppa processes that have had
  incoming remote connections fail during the binding phase of
  the connection request.
  
  Platforms affected:
  All Distributed (iSeries, all Unix and Windows)
  ****************************************************************
  PROBLEM SUMMARY:
  Memory allocated in anticipation of a successful connection is
  not freed in the event of a specific failure condition during
  the connection request.
  

Problem conclusion

• The function where the memory is allocated has been updated to
  check for the error condition before exiting, and frees the
  memory that was previously allocated in the event that the error
  condition is identified.
