Hi Joseph, Cluster state changes are not allowed when we do not know for sure that the cluster has got a consistent view of the cluster state, this could make it impossible to leave the cluster until those nodes are marked DOWN or become reachable again.
Could this be what is causing your problems or was the cluster in good shape before you tried to leave using the command line tool? (http://doc.akka.io/docs/akka/2.4.1/common/cluster.html#Gossip_Convergence) I would take a look at the cluster state after issuing leave to see what is going on, you can do that with the same tool and "cluster-status". I hope this helps! -- Johan Andrén Typesafe - Reactive apps on the JVM Twitter: @apnylle On Tuesday, January 12, 2016 at 2:03:24 PM UTC+1, jos...@evernym.us wrote: > > Hi, > > I have a 2-node akka cluster.
