Shortly after my app starts up I see this in the logs:
INFO akka.actor.DeadLetterActorRef - Message [java.lang.String] from Actor[akka://MyApp/user/sqs-poller/router#-923782747] to Actor[akka://MyApp/deadLetters] was not delivered. [1] dead letters encountered. This logging can be turned off or adjusted with configuration settings 'akka.log-dead-letters' and 'akka.log-dead-letters-during-shutdown'.
Does this mean the router was sent a shutdown command? Is it possible to have akka log the dead letters?
