> {*}Problem{*}:
> When ambari agent is not reporting to server for a period of time and tries
> to resume the reporting, Ambari Server requests agent auto restart action.

> state.
> {*}Problematic code{*}:
> Utils.py
> {code:java}
> def restartAgent(stop_event, graceful_stop_timeout=30):
> ExitHelper().exitcode = AGENT_AUTO_RESTART_EXIT_CODE
> stop_event.set()
> t = threading.Timer( graceful_stop_timeout, ExitHelper().exit,
> [AGENT_AUTO_RESTART_EXIT_CODE])
> t.start() {code}
> *Fix:*
> {code:java}
> def restartAgent(stop_event, graceful_stop_timeout=30):
> exit_helper = ExitHelper()
> exit_helper.exitcode = AGENT_AUTO_RESTART_EXIT_CODE
> stop_event.set()
> t = threading.Timer( graceful_stop_timeout, exit_helper.exit)
