Hi There,
I was running ES 2.4 with cluster 3 nodes. The cluster is working till this day my ES service is Service Unavailable and I caught log below.
## My ES conifig
## [cluster.name](http://cluster.name): production [node.name](http://node.name): ${HOSTNAME} node.master: true node.data: true path.data: /home/elasticsearch/data path.logs: /home/elasticsearch/logs bootstrap.mlockall: true network.host: [_p2p1_, _local_] network.bind\_host: 0.0.0.0 discovery.zen.ping.unicast.hosts: ["elk", "elk-node1", "elk-node2"] discovery.zen.ping.multicast.enabled: false discovery.zen.minimum\_master\_nodes: 2
Log: I was cut some line out because the message over 5000 words.
