Hi Emily, If an actor is blocking a thread and never returns it to the ActorSystem cannot do much about it, and if you try to terminate the ActorSystem it will never complete terminating.
Blocking a thread could be actual processing that never stops or just takes a very long time, being stuck reading or writing some blocking resource, etc. You should be able to see what is going on by connecting to the JVM and taking a thread dump - this should show at least one thread having a call stack into one of your actors. -- Johan Andrén Akka Team, Lightbend Inc.
