The random connection issues continue to plague my production systems. Now that I've brought up a second remote server, I'm getting the following errors: [2012-04-18 10:13:50,398][WARN][cluster.service] [app1-uk- example-com] failed to reconnect to node [app2-uk-example-com] [HRCQGb4lTIm-hjzENY3mTQ][inet[/172.28.5.3:9300]]{zone=uk} org.elasticsearch.transport.ConnectTransportException: [app2-uk- example-com][inet[/172.28.5.3:9300]] connect\_timeout[30s] at org.elasticsearch.transport.netty.NettyTransport.connectToChannels(NettyTransport.java: 560) at org.elasticsearch.transport.netty.NettyTransport.connectToNode(NettyTransport.java: 503) at org.elasticsearch.transport.netty.NettyTransport.connectToNode(NettyTransport.java: 482) at org.elasticsearch.transport.TransportService.connectToNode(TransportService.java: 128) at org.elasticsearch.cluster.service.InternalClusterService $ReconnectToNodes.run(InternalClusterService.java:377) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java: 1110) at java.util.concurrent.ThreadPoolExecutor $Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:679) Caused by: java.net.ConnectException: Connection refused at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method) at sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:592) at org.elasticsearch.common.netty.channel.socket.nio.NioClientSocketPipelineSink $Boss.connect(NioClientSocketPipelineSink.java:400) at org.elasticsearch.common.netty.channel.socket.nio.NioClientSocketPipelineSink $Boss.processSelectedKeys(NioClientSocketPipelineSink.java:362) at org.elasticsearch.common.netty.channel.socket.nio.NioClientSocketPipelineSink $Boss.run(NioClientSocketPipelineSink.java:284) at org.elasticsearch.common.netty.util.ThreadRenamingRunnable.run(ThreadRenamingRunnable.java: 102) at org.elasticsearch.common.netty.util.internal.DeadLockProofWorker $1.run(DeadLockProofWorker.java:42) So the two UK servers won't talk to each other, and the status info on app1 show green but no shards, and the status info on app2 shows proper sharding and a green cluster. I'm happy to pay someone to help me debug this problem - does anyone offer paid ES support? ---

Do you have any firewall or something that can block the two nodes from talking to one antoher?

No, there was no firewall. The UK servers had multiple aliased IPs and the ES server was taking one of the aliases because I did not have a specific IP configured. This works on boxed with only one IP but not multiple. Once I put the non-alias IP in the config, they could talk to each other. The aliased IP work fine otherwise for other servers. ---
