Error description

  • The nodeagent trace shows that the process is terminated:

    NodeAgent calls waitForTermination, and since the process object
    is already released, that exception is thrown:

    When terminating an application server process, a
    ProcessOpException is thrown if the process object is already
    released indicating that the process is already released and
    no further call is allowed:
    Stack Dump = javax.management.MBeanException: null nested

Problem conclusion

  • Code has been changed to catch this exception an not throw it
    as an AdminException since, when the process object is
    released, the process is already terminated.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 6.1.0.41, 7.0.0.21 and 8.0.0.1. Please refer to the
    recommended updates page for delivery information:
    http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980.
    
    For V6.0.2, an interim fix will be available upon request.
