APAR status

  • Closed as program error.

Error description

  • If the server is terminated abnormally where the normal
    server shutdown is skipped (ex. "kill -9 <server pid>"),
    then some native threads may be in a z/OS PAUSE service.
    These threads will not be terminated by LE.   The result is
    that the server does not terminate and may continue to hold
    resources such as ports and storage.

    If the server is terminated abnormally where the normal
    server shutdown is skipped (ex. "kill -9 <server pid>"),
    then some native threads may be in a z/OS PAUSE service.
    These threads will not be terminated by LE.   The result is
    that the server does not terminate and may continue to hold
    resources such as ports and storage.
    

Problem conclusion

  • Code has been added to manage a dedicated cleanup thread.  This
    new cleanup thread will trigger cleanup routines that will
    release known users of the z/OS PAUSE service that would have
    hung up the termination of the server in the event of a hard
    server failure.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.1.  Please refer to the Recommended Updates page for
