    * PROBLEM DESCRIPTION: SIP transaction is not being removed    *
    *                      from memory when the application is     *

    * RECOMMENDATION:                                              *
    ****************************************************************
    If the application uses a ProxyTimer, the SIP transaction
    is not being cleaned from memory after application was
    undeployed.
    

Problem conclusion

  • This fix prevents a leak of SIP transaction after application
    is undeployed.
    The leak occurs because the java Timer object holds a
    reference to a SIP TimerTask instance even though the
    TimerTask was already canceled.
    The fix nullifies the TimerTask when it is being canceled and
    prevents it from staying in the memory along with all
    it's references including SIP transaction objects.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.5.5.4.  Please refer to the Recommended Updates
