Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Liberty who use JAX-WS Web Services  *
    ****************************************************************
    * PROBLEM DESCRIPTION: Memory leak in                          *
    *                      org.apache.cxf.transport.http.osgi.HTTP *

    * RECOMMENDATION:                                              *
    ****************************************************************
    When Liberty JAX-WS Web service was invoked multiple times,
    memory leak was detected after a few days in the
    org.apache.cxf.transport.http.osgi.HTTPTransportActivator$PidInf
    o class.  After about 10 days of running there were 448,225
    instances of this PidInfo class using 84 MB of memory
    

Problem conclusion

  • The memory leak occurred because the memory allocated for the
    org.apache.cxf.transport.http.osgi.HTTPTransportActivator$PidInf
    o class was not cleaned up properly. This problem was resolved
    by freeing the memory for the instances of PidInfo class that
    were not used anymore.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.3.  Please refer to the Recommended Updates page for
    delivery information:
