Hello, I have elastic cluster, created from 8 hot nodes, 4 warm nodes, 3 masters and 2 coordinating nodes. I still getting error on some node (randomize), when its disconnected. ``` [2018-09-11T07:38:48,692][ERROR][o.e.b.ElasticsearchUncaughtExceptionHandler] [elk-es-data-hot-1.osdc2.company.local] fatal error in thread [elasticsearch[elk-es-data-hot-1.osdc2.company.local][bulk][T#4]], exiting java.lang.AssertionError: Unexpected AlreadyClosedException at org.elasticsearch.index.engine.InternalEngine.failOnTragicEvent(InternalEngine.java:1786) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.index.engine.InternalEngine.maybeFailEngine(InternalEngine.java:1803) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.index.engine.InternalEngine.index(InternalEngine.java:905) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.index.shard.IndexShard.index(IndexShard.java:738) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.index.shard.IndexShard.applyIndexOperation(IndexShard.java:707) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.index.shard.IndexShard.applyIndexOperationOnReplica(IndexShard.java:680) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.action.bulk.TransportShardBulkAction.performOpOnReplica(TransportShardBulkAction.java:518) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.action.bulk.TransportShardBulkAction.performOnReplica(TransportShardBulkAction.java:480) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.action.bulk.TransportShardBulkAction.shardOperationOnReplica(TransportShardBulkAction.java:466) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.action.bulk.TransportShardBulkAction.shardOperationOnReplica(TransportShardBulkAction.java:72) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.action.support.replication.TransportReplicationAction$AsyncReplicaAction.onResponse(TransportReplicationAction.java:567) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.action.support.replication.TransportReplicationAction$AsyncReplicaAction.onResponse(TransportReplicationAction.java:530) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.index.shard.IndexShard$2.onResponse(IndexShard.java:2315) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.index.shard.IndexShard$2.onResponse(IndexShard.java:2293) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.index.shard.IndexShardOperationPermits.acquire(IndexShardOperationPermits.java:238) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.index.shard.IndexShard.acquireReplicaOperationPermit(IndexShard.java:2292) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.action.support.replication.TransportReplicationAction$AsyncReplicaAction.doRun(TransportReplicationAction.java:641) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.common.util.concurrent.AbstractRunnable.run(AbstractRunnable.java:37) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.action.support.replication.TransportReplicationAction$ReplicaOperationTransportHandler.messageReceived(TransportReplicationAction.java:513) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.action.support.replication.TransportReplicationAction$ReplicaOperationTransportHandler.messageReceived(TransportReplicationAction.java:493) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.transport.RequestHandlerRegistry.processMessageReceived(RequestHandlerRegistry.java:66) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.transport.TcpTransport$RequestHandler.doRun(TcpTransport.java:1555) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.common.util.concurrent.ThreadContext$ContextPreservingAbstractRunnable.doRun(ThreadContext.java:672) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.common.util.concurrent.AbstractRunnable.run(AbstractRunnable.java:37) ~[elasticsearch-6.2.3.jar:6.2.3] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) ~[?:1.8.0_144] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) ~[?:1.8.0_144] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_144] Caused by: org.apache.lucene.store.AlreadyClosedException: translog is already closed at org.elasticsearch.index.translog.Translog.ensureOpen(Translog.java:1667) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.index.translog.Translog.add(Translog.java:508) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.index.engine.InternalEngine.index(InternalEngine.java:887) ~[elasticsearch-6.2.3.jar:6.2.3] ... 24 more ``` This is my default template for new indices: { "default" : { "order" : -1, "index\_patterns" : [ "\*" ], "settings" : { "index" : { "codec" : "best\_compression", "routing" : { "allocation" : { "include" : { "type" : "hot" } } }, "mapping" : { "total\_fields" : { "limit" : "4000" } }, "refresh\_interval" : "30s", "number\_of\_shards" : "4", "translog" : { "durability" : "async" }, "number\_of\_replicas" : "1" } }, "mappings" : { }, "aliases" : { } } } What causes this problem and how to solve it?
