Hi Team,

I have created a 3 node elasticsearch setup. One of my docker container fails with the below error

Hi @tamilarasanbravo

It usually helps to post your config files / docker compose etc..

The error seems to indicate that the JVM heap settings are not equal.

https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html

Elasticsearch will assign the entire heap specified in jvm.options via the Xms (minimum heap size) and Xmx (maximum heap size) settings. You should set these two settings to be equal to each other.
