Basically depending on your dataset, it will require more memory or more nodes. ES\_HEAP\_SIZE=256m is just too low. Start with at least 1Gb RAM As you have a 4Gb machine, you can set it to 2 Gb. If it's a production machine, you should not run other IO heavy services on the same physical box (such as database).

Hi David, I'm trying to move Elasticsearch on a new system, but while trying to start the service its giving below exception. Althrough the process is running. There was old elasticsearch 0.90 copied which is not running now as I checked. Please suggest.
