In case there’s interest from other’s, here’s an updated implementation that gets the results I want using the approach suggested by Evgeniy:
https://gist.github.com/metasim/0ea9de220fb0ac1aef41 I /am/ getting three deadLetter messages of this form: 10:41:50 INFO [default-akka.actor.default-dispatcher-7] a.a.RepointableActorRef - Message [akka.stream.impl.RequestMore] from Actor[akka://default/deadLetters] to Actor[akka://default/user/flow-2-1-map#2007922913] 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'. Not sure if they’re problems; I wasn’t able to track down where they’re coming from (some internal API) or how to ensure they don’t occur.
