I have a cluster setup with three nodes. The three nodes are setup within LXC with 8GB of ram dedicated to each container. Heap size is set to 4GB on each and bootstrap.mlockall is set to true. iptables has been setup to forward incoming traffic on port 9200 to the master node. Heres an image of the diagnostics provided by HQ. [http://i.imgur.com/z59W4hV.png](http://i.imgur.com/z59W4hV.png) I experience quite a few timeouts. The dedicated server is a 48GB RAM setup with 8 cores and SSD disks, so I would believe I have enough power to handle the load. Can anyone see if there is something I should be aware of or something that I can do to make my Thank you. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Can you elaborate on the timeouts? What Elasticsearch version, what java version?

Hi Mark, Java: java version "1.7.0\_55" OpenJDK Runtime Environment (IcedTea 2.4.7) (7u55-2.4.7-1ubuntu1~0.13.10.1) ES is version 1.2.1 The timeouts happen when higher number of queries occur and ES has memory issues. But I'm unsure as to why the setup lacks memory.

If you have one server with 48G RAM / 8 cores / SSD you should se up one Elasticsearch node because JVM is capable of managing it. By setting up 3 nodes on just a single server, you only add overhead and the risk of timeouts and instability is higher.
