Exception: java.lang.OutOfMemoryError: Java heap space

Elastic Stack Elasticsearch

Hi.
I am running ElasticSearch 6.1.3 in a Liferay Installation and I am facing an Exception "java.lang.OutOfMemoryError: Java heap space" that is causing malfunction in Liferay portal.

That's the information I have collected:

    curl -X GET "http://pvmtelastila1:9200/"
    {
      "name" : "pvmtelastila1",
      "cluster_name" : "LiferayCluster",
      "cluster_uuid" : "K2FHedK2T9ulV5bbznxOWw",
      "version" : {
        "number" : "6.1.3",
        "build_hash" : "af51318",
        "build_date" : "2018-01-26T18:22:55.523Z",
        "build_snapshot" : false,
        "lucene_version" : "7.1.0",
        "minimum_wire_compatibility_version" : "5.6.0",
        "minimum_index_compatibility_version" : "5.0.0"
      },
      "tagline" : "You Know, for Search"
    }

Any suggestions are appreciated.

Welcome to our community! :smiley:
Please be aware that 6.3 reached EOL in late 2019. You should upgrade as a matter of urgency.

There should be something in your Elasticsearch logs for this, can you post them?
