Hello All,
I am setting akka cluster *(using akka library version 2.3.9* ) with one
master actor and multiple worker actor. Master Actor is configured with
pool cluster aware router.
I am deploying application with forming 4 cluster nodes. *Initially all the
nodes are joining to cluster properly but after few minutes nodes are
leaving to cluster and forming their own cluster. *
Getting below *warn *message when i add another node in the cluster.
*[WARN*] [08/22/2016 04:52:42.145]

Association with remote system [akka.tcp://ClusterSystem@host:port] has
failed, address is now gated for [5000] ms. Reason is: [Failed to write

And *after few minutes of joining, * frequent unreachable reachable
*warning *message is getting logged.

Please let me know if i am missing any configuration.
*My application.conf is configured as below-*
my-dispatcher {
type = PinnedDispatcher
executor = "thread-pool-executor"
thread-pool-executor {
core-pool-size-min = 1
core-pool-size-factor = 2.0
core-pool-size-max = 2
}
throughput = 3
mailbox-capacity = 3
}
akka {
bounded-mailbox {
mailbox-type = "akka.dispatch.BoundedMailbox"
mailbox-capacity = 2
mailbox-push-timeout-time = 100ms
}
actor {
provider = "akka.cluster.ClusterActorRefProvider"
serializers {
akka-cluster = "akka.cluster.protobuf.ClusterMessageSerializer"
}
serialization-bindings {
"akka.cluster.ClusterMessage" = akka-cluster
"org.springframework.context.support.ClassPathXmlApplicationContext" =
akka-cluster
}
}
remote {
log-remote-lifecycle-events = off
netty.tcp {
hostname = ${akka.node.hostname}
port = ${akka.node.port}
}
}
cluster {
seed-nodes = [${akka.seed.nodes}]
roles = ["master"]
auto-down-unreachable-after = 10s
}
}
akka.actor.deployment {
/singleton/MyConsumerActor/workerRouter {
router = consistent-hashing-pool
nr-of-instances = 100
cluster {
enabled = on
max-nr-of-instances-per-node = 3
allow-local-routees = on
use-role = master
}
}
}
*//tried with customizing transport-failure-detector*
akka.remote.transport-failure-detector {
heartbeat-interval = 1000s
acceptable-heartbeat-pause = 6000s
}
Thanks,
Vipin Mandloi
