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.

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.
