             Summary: Patch for commons-daemon 1.0.15 to avoid shutdown failures
                 Key: DAEMON-339
                 URL: https://issues.apache.org/jira/browse/DAEMON-339
             Project: Commons Daemon
          Issue Type: Bug
          Components: Jsvc
    Affects Versions: 1.0.15
         Environment: Multiple UNIX platforms ... E.g.:
Red Hat ES 6
Solaris 10 x64
            Reporter: John Wehle
            Priority: Minor


We've seen situations on UNIX where JSVC will fail to shutdown when
requested ... in at least one case this caused the machine to hang
during shutdown.

On UNIX JSVC automatically restarts the JVM if it crashes.  Currently
this means that if the JVM crashes after receiving a shutdown request
(i.e. a SIGINT), then it's restarted by the controller which is not
what's desired.

The enclosed patch propagates the termination request from the JVM to
the controller so that the controller knows not to schedule a restart
thus allowing JSVC to actually terminate.

Granted this doesn't fix the underlying problem of the JVM crashing
during shutdown, however that's a separate (potentially application
specific) issue.

Tested by using a dummy JAVA service containing an endless loop in
the shutdown code.  Test sequence was:

  jsvc ... -verbose -debug hello.MyDaemon
  kill -INT `cat pidfile`
  # notice that output showed shutdown running
  kill -BUS `cat pidfile`
  # notice that prior to patch output showed restart being scheduled
