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

Ideally elastic search jvm needs more memory for faster processing and querying multiple shards. However, the jvm size should not be more than the system memory size. Change the memory for elastic search as per your configuration in

/etc/elasticsearch/jvm.options:

-Xms4g (Minimum memory) -Xmx4g (Maximum memory)

Set it to the exactly half of the machine memory for ideal use
