Hi Patrik,

Have you seen this before? It is happening on one PC but not in the other, 
I changed *advanced.idle-cpu-level* to 3, got that error, then removed that 
setting and recompiled but still getting the following exception:

ERROR 11:05:07,979 ArteryTransport(akka://DevCluster) - Aeron error: 8

My remote config:
  remote {
    log-remote-lifecycle-events = off

    artery {
      enabled = on
      port = 0
    }

    default-remote-dispatcher {
      type = Dispatcher
      executor = "fork-join-executor"

      fork-join-executor {
        parallelism-min = 8
        parallelism-factor = 1.0
        parallelism-max = 16
      }
    }
  }


Cheers,

Guido.
