Timeout on Elasticsearch

Elastic Stack Elasticsearch
1

Hi,

I have every day timeout on plugin elasticsearch of 3000ms.
In the log I see

[2016-07-01 09:43:16,311][WARN ][indices.ttl              ] [Franklin Hall] failed to execute ttl purge
java.lang.OutOfMemoryError: Java heap space
[2016-07-01 09:43:16,311][WARN ][threadpool               ] [Franklin Hall] failed to run org.elasticsearch.index.shard.IndexShard$EngineRefresher@672074
java.lang.OutOfMemoryError: Java heap space
[2016-07-01 09:43:42,982][WARN ][netty.channel.socket.nio.AbstractNioSelector] Failed to accept a connection.
java.lang.OutOfMemoryError: Java heap space

So I want to increase heap size (https://www.elastic.co/guide/en/elasticsearch/guide/current/heap-sizing.html)
I put this command in /etc/init.d/elasticsearch

export ES_HEAP_SIZE=3g

My server have 8Gb of ram.
If I put more than 3Gb, I have this error:

[root@x elasticsearch]# /etc/init.d/elasticsearch restart
Stopping elasticsearch:                                    [  OK  ]
Starting elasticsearch: Invalid initial heap size: -Xms4g
The specified size exceeds the maximum representable size.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.                                     [FAILED]

In kibana configuraiton, I have

 elasticsearch.pingTimeout: 5000
 elasticsearch.requestTimeout: 50000

Can you help me ?

Thanks

I suspect that you're running a 32-bit JVM by default and that is leading to the error message that you're seeing. You can try forcing a 64-bit server JVM by adding the flags -server -d64 to ES_JAVA_OPTS on startup.

Thanks!
I use a 32bits version of java, so I reinstall it with a 64 bits versions.
