    ****************************************************************
    The WebSphere activity service is used by a number of high
    level services such as CScopes, Workarea and Activity
    Sessions. When one of these services is active on a thread and
    a remote call is made, then the leaking objects are added to a
    HashMap and HashTable with the Java and WebSphere ORB code.
    These objects were then never unregistered from these
    collections.
    

Problem conclusion

  • This APAR solves the problem by explicitly removing the
    CoordinatorProxyWrapper objects registered with the ORB.
    
    APAR PM64521 is currently targeted for inclusion in Fix Packs
    7.0.0.25, 8.0.0.5, and 8.5.0.1 of WebSphere Application
    Server.
