Using ES 19.3 and ES\_HEAP\_SIZE=1g Node stats are here [https://gist.github.com/2893236](https://gist.github.com/2893236) Info is here [https://gist.github.com/2893271](https://gist.github.com/2893271) The longer this runs the more memory gets used, currently 2.5g. Utilization of elasticsearch is very low, just 1 shard and a handful of documents and searches What are the recommended steps to determine if this is a real problem? and if so is there anything that can be done to minimize memory use? ---

It does not use memory at all on the JVM level (you can see the heap\_used part there). Do you have any special configuration or index level configuration?

Yes heap used appears low but "ps aux" report 2gb resident and 4gb virtual for elasticsearch No special configuration, on IRC it was recommended that I try a different JVM. Currently using openjdk will be trying oracle 7 On Sun, Jun 10, 2012 at 4:45 PM, Shay Banon [kimchy@gmail.com](mailto:kimchy@gmail.com) wrote: > It does not use memory at all on the JVM level (you can see the heap\_used > part there).
