Hi
<div><br></div><div>I have a series of MultiService objects, with child Services. Some of these services are TCPServers, for example, and others are my own objects (extending from Service).</div><div>In the instance that I have a Service which controls a LoopingCall, I am getting intermittent 'unclean reactor' errors during tests. I feel I might be missing some handling of deferreds, perhaps.</div>
<div>(using 8.2.0 - looking to migrate to 10.2.0 soon)</div><div><br></div><div>Here is an example of the approach being used:</div><div><br></div><div>class AdapterQueue(service.MultiService):</div><div><div> def startService(self):</div>
<div> service.Service.startService(self)</div><div> self._looping_controller = LoopingCall(self._action)</div><div> d = self._looping_controller.start(self.delay, False)</div><div> d.addErrback(self._errorInScheduler)</div>
</div><div><br></div><div><div> def stopService(self):</div><div> service.Service.stopService(self)</div><div> d = self._looping_controller.deferred</div><div> self._looping_controller.stop()</div>
<div> return d</div></div><div><br></div><div>And an example error (happens about 1/3 of the time):</div><div><br></div><div><div>DirtyReactorAggregateError: Reactor was unclean.</div><div>DelayedCalls: (set twisted.internet.base.DelayedCall.debug = True to debug)</div>
