[akka-user] Akka EC2 remoting

[Stefan Schmidt]

Hi guys,


We have setup an Akka cluster in EC2 following the setup described here 
. The 
main purpose is to use it for creating cluster singletons to perform a 
number of batch tasks. We also use Websocket support in Play framework 
backed by Actors.

All works well, except we see a large number of warn messages which concern 
me.

[WARN] - from akka.remote.ReliableDeliverySupervisor in 
application-akka.actor.default-dispatcher-7
Association with remote system [akka.tcp://akka-ec2@127.0.0.1:2551] has 
failed, address is now gated for [5000] ms. Reason is: [Association failed 
with [akka.tcp://akka-ec2@127.0.0.1:2551]].

The akka configuration we use is fairly straight foward
akka {
  actor {
provider = "akka.cluster.ClusterActorRefProvider"
debug {
  lifecycle = off
  router-misconfiguration = on
  unhandled = on
}
  }
  remote {
log-remote-lifecycle-events = off
netty.tcp {
  hostname = ""
  port = 0
}
log-received-messages = on
log-sent-messages = on
transport-failure-detector {
  heartbeat-interval = 8 s   # default 4s
  acceptable-heartbeat-pause = 12 s  # default 10s
}
  }
  cluster {
seed-nodes = ["akka.tcp://akka-ec2@127.0.0.1:2551"]
auto-down-unreachable-after = 10s
retry-unsuccessful-join-after = off
roles = ["worker"]
  }
  log-config-on-start = off
  log-dead-letters = 10
  log-dead-letters-during-shutdown = on
  loggers = ["akka.event.slf4j.Slf4jLogger"]//, 
"akka.event.Logging$DefaultLogger"]
  loglevel = DEBUG

  stdout-loglevel=DEBUG
}

Any ideas why we see these warn messages (one every 5 seconds per node)? 

Thanks,
Stefan

Looks like you're trying to connect to a seed that isn't available. Be sure 
that your remote.netty.tcp host and port settings match your seed node setting. 
 They don't seem to here.
