Hi All, I see below error logs in ES, can you please guide why one might get the below exception I am using ES 2.3.3 Heap size is 6G [ep\_fo\_people\_search\_e92pbg01][[ep\_fo\_people\_search\_e92pbg01][1]] TranslogException[Failed to write operation [Create{id='[http://plef4001.us.com:8000/psc/e92pbg01x\_newwin/EMPLOYEE/E92PBG01/c/FO\_EMPLOYEE.FO\_EMPLOYEE.GBL?Page=FO\_EMP\_PERS\_DATA1&Action=U&EMPLID=XE009100000](http://plef4001.us.com:8000/psc/e92pbg01x_newwin/EMPLOYEE/E92PBG01/c/FO_EMPLOYEE.FO_EMPLOYEE.GBL?Page=FO_EMP_PERS_DATA1&Action=U&EMPLID=XE009100000)', type='ep\_fo\_people\_search\_e92pbg01'}]]; nested: OutOfMemoryError[Java heap space]; at org.elasticsearch.index.translog.Translog.add(Translog.java:557) at org.elasticsearch.index.engine.InternalEngine.innerCreateNoLock(InternalEngine.java:440) at org.elasticsearch.index.engine.InternalEngine.innerCreate(InternalEngine.java:378) at org.elasticsearch.index.engine.InternalEngine.create(InternalEngine.java:349) at org.elasticsearch.index.shard.IndexShard.create(IndexShard.java:545) at org.elasticsearch.index.engine.Engine$Create.execute(Engine.java:810) at org.elasticsearch.action.index.TransportIndexAction.executeIndexRequestOnPrimary(TransportIndexAction.java:237) at org.elasticsearch.action.bulk.TransportShardBulkAction.shardIndexOperation(TransportShardBulkAction.java:326) at org.elasticsearch.action.bulk.TransportShardBulkAction.shardUpdateOperation(TransportShardBulkAction.java:389) at org.elasticsearch.action.bulk.TransportShardBulkAction.shardOperationOnPrimary(TransportShardBulkAction.java:191) at org.elasticsearch.action.bulk.TransportShardBulkAction.shardOperationOnPrimary(TransportShardBulkAction.java:68) at org.elasticsearch.action.support.replication.TransportReplicationAction$PrimaryPhase.doRun(TransportReplicationAction.java:639) at org.elasticsearch.common.util.concurrent.AbstractRunnable.run(AbstractRunnable.java:37) at org.elasticsearch.action.support.replication.TransportReplicationAction$PrimaryOperationTransportHandler.messageReceived(TransportReplicationAction.java:279) at org.elasticsearch.action.support.replication.TransportReplicationAction$PrimaryOperationTransportHandler.messageReceived(TransportReplicationAction.java:271) at org.elasticsearch.transport.RequestHandlerRegistry.processMessageReceived(RequestHandlerRegistry.java:75) at org.elasticsearch.transport.TransportService$4.doRun(TransportService.java:376) at org.elasticsearch.common.util.concurrent.AbstractRunnable.run(AbstractRunnable.java:37) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.OutOfMemoryError: Java heap space ---

``` OutOfMemoryError: Java heap space ``` Not enough HEAP available apparently. Why? No idea without knowing anything about your cluster. ---

Hi, I have a single node ES 2.3.2 cluster with 6G Heap running on Redhat 6.x machine. I am indexing docs using bulk api. Using curl 50 parallel bulk requests are hitting ES and each of size 12MB-15MB approx. after indexing around 1.7 million docs, i see Java OOM issue and I see the below info statements in logs java.lang.OutOfMemoryError: Java heap space [2017-05-31 20:15:31,535][INFO][monitor.jvm] [pleej09\_1] [gc][old][17986][7548] duration [5.2s], collections [1]/[5.5s], total [5.2s]/[11.1h], memory [5.7gb]-\>[5.7gb]/[5.8gb], all\_pools {[young] [1.4gb]-\>[1.4gb]/[1.4gb]}{[survivor] [173.4mb]-\>[150.1mb]/[191.3mb]}{[old] [4.1gb]-\>[4.1gb]/[4.1gb]} [2017-05-31 20:15:42,188][INFO][monitor.jvm] [pleej09\_1] [gc][old][17988][7550] duration [5.3s], collections [1]/[5.7s], total [5.3s]/[11.1h], memory [5.7gb]-\>[5.7gb]/[5.8gb], all\_pools {[young] [1.4gb]-\>[1.4gb]/[1.4gb]}{[survivor] [157.8mb]-\>[167.2mb]/[191.3mb]}{[old] [4.1gb]-\>[4.1gb]/[4.1gb]} when I look into stats I see the below values in GC section timestamp: 1496287486120, uptime\_in\_millis: 56616425, mem: { heap\_used\_in\_bytes: 6140054600, heap\_used\_percent: 98, heap\_committed\_in\_bytes: 6241845248, heap\_max\_in\_bytes: 6241845248, non\_heap\_used\_in\_bytes: 125976480, non\_heap\_committed\_in\_bytes: 128987136, pools: { young: { used\_in\_bytes: 1605304320, max\_in\_bytes: 1605304320, peak\_used\_in\_bytes: 1605304320, peak\_max\_in\_bytes: 1605304320 }, survivor: { used\_in\_bytes: 99034656, max\_in\_bytes: 200605696, peak\_used\_in\_bytes: 200605696, peak\_max\_in\_bytes: 200605696 }, old: { used\_in\_bytes: 4435935232, max\_in\_bytes: 4435935232, peak\_used\_in\_bytes: 4435935232, peak\_max\_in\_bytes: 4435935232 } } } My question is why GC is not releasing memory and memory is growing continuously. Apart from indexing, no other activities being carried out on ES. Also I use mapper attachment plugin in my ES as my docs contains attachments. ---
