Hi Patrick, Sorry for not being very clear. I am using Akka together with Play. I have two Play applications that both create actors. These actors use Akka remote to communicate with each other. During my initial tests, I was launching the play applications using "sbt run" and when I was closing one Play application, the other crashed with the [error] a.r.EndpointWriter - AssociationError that I described in my initial post. This problem disappears when I compile the apps instead of launching them from sbt.
Once this initial "problem" solved, I still needed to detect when the connection to the remote actor is lost, this problem was solved by subscribing to the right event stream.
