I have the following hierarchy of actions:
receiverResponsible for handling HTTP requests. When a request arrives, this actor creates a child actor coordinator(actually with a dynamic name).
After completing coordinatorhis work, he performs Context.Stop(Self). This gracefully stops all children, but then I get the following messages in the console:
[INFO] [05.23.2016 08:48:45] [Topic 0013] [akka: // FSharpSystem / user / receiver / $ b] DeathWatchNotification message from akka: // FSharpSystem / user / receiver / $ b to akka: / / FSharpSystem / user / receiver / $ b not delivered. 1 dead letters found.
