Scala version: 2.10
Akka version: 2.2-SNAPSHOT

Hi,

I have been trying to run the sample akka-cluster code found at http://doc.akka.io/docs/akka/snapshot/cluster/cluster-usage-scala.html#A_Simple_Cluster_Example, modified to have a single seed node.

Problem scenario:
1. I start a single seed node at port 2551
2. I start another node at random port. Both nodes connect and are up
3. I then kill the second node.
4. Instead of detecting the second node failure and moving it to down state, the following error is logged:

[ERROR] [02/27/2013 13:08:06.487] [ClusterSystem-akka.remote.writer-dispatcher-11] [akka://ClusterSystem/system/endpointManager/endpointWriter-akka.tcp%3A%2F%2FClusterSystem%40127.0.0.1%3A49864-0] Disassociated
akka.remote.EndpointException: Disassociated

and then repeatedly:

[ERROR] [02/27/2013 13:08:07.563] [ClusterSystem-akka.remote.writer-dispatcher-11] [akka://ClusterSystem/system/endpointManager/endpointWriter-akka.tcp%3A%2F%2FClusterSystem%40127.0.0.1%3A49864-0] Association failed with [akka.tcp://ClusterSystem@127.0.0.1:49864]
akka.remote.EndpointException: Association failed with [akka.tcp://ClusterSystem@127.0.0.1:49864]
Caused by: akka.remote.transport.netty.NettyTransport$$anonfun$associate$1$$anon$2: Connection refused: no further information

I have left it running for several minutes hoping hoping that it will eventually move that node to removed state, but this error just continues being logged.
