Hi Wolfgang, you mentioned that when you set up a separate dispatcher for a cluster, you started to see less problems in a cluster behavior. This indicates that some part of your application missuses precious threads of a default akka dispatcher. Try to identify these spots and use a dedicated dispatcher for these activities, leaving akka default dispatcher available for akka internals.
