------------------------------------

             Summary: DUCC SM should mark custom pingers so they're more easily reaped.
                 Key: UIMA-3707
                 URL: https://issues.apache.org/jira/browse/UIMA-3707
             Project: UIMA
          Issue Type: Improvement
          Components: DUCC
            Reporter: Jim Challenger
            Assignee: Jim Challenger
            Priority: Minor


If the Service Manager is killed-with-prejudice it can leave CUSTOM pingers alive and orphaned
(children of init).

SM should clearly mark these processes so cleanup procedures can easily find them and reap
them as part of system startup.  The proposed mechanism is to set a -Dmarker as a no-op system
property to ServicePingMain that is easily discovered using ps.  Startup scripting (and check_ducc)
will look for these processes and kill them prior to starting SM.

As well SM should implement a shutdown hook that attempts to stop these pingers if it is stopped
with only-a-little-prejudice.
