Elasticsearch memory problems

Question

When I\'m trying too start the elasticsearch in my Ubuntu the startup script gives me the following error:

Java HotSpot(TM) Client VM warning: INFO: os::comm         


        

Answer 1

You have configured a virtual machine with 1 GB of RAM, but elastic is trying to start with 2 GB of RAM (default for Elasticsearch version 5.X)

Either give more memory to your VM, or change Elasticsearch JVM settings /etc/elasticsearch/jvm.options and lower the values of the following parameters: -Xms512m -Xmx512m
