APAR status

  • Closed as program error.

Error description

  • The existing classloader leak detection only detects leaks
    for applications that were not dynamically stopped prior
    to server shutdown.  If an application leaked its classloader
    but was stopped prior to server shutdown, that leak would not
    be detected.
    
    Classloader leak detection is enabled by specifying the
    following system property:
      -Dcom.ibm.ws.runtime.detectAppCLLeaks=true

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server V7.0 and V8.0                        *
    ****************************************************************
    * PROBLEM DESCRIPTION: Leaked application classloaders         *
    *                      stopped prior to server shutdown are    *
    *                      not detected.                           *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The classloader detection feature in the application server
    will detect leaked application classloaders during server
    shutdown.  However, if the application was stopped prior to
    shutting down the server, that application's classloader may
    have been leaked, but would not be detected.
    

Problem conclusion

  • This APAR improves the classloader leak detection feature by
    detected application classloaders that were stopped prior to
    server shutdown.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.19 and 8.0.0.1.  Please refer to the
    Recommended Updates page for delivery information:
