hello! I am trying to troubleshoot elasticsearch, we noticed that it was having memory issues and crashing. We have added 4gbs of memory onto the server but notice that it is not using the additional resources, is there a way to increase the memory elasticsearch uses or perhaps a way to set the entire stack to use the available resources evently?

Hi @Luis_Alejandro_Galan,

You can set the [heap size](https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html) that elasticsearch will use in the `jvm.options` [configuration](https://www.elastic.co/guide/en/elasticsearch/reference/current/jvm-options.html) file. In those links above you will find the recommended value based on the total memory available too.

I hope it helps!
