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:
```auto
curl -X GET "http://pvmtelastila1:9200/"
{

"cluster_name" : "LiferayCluster",

"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! 😃
Please be aware that 6.3 reached [EOL](https://www.elastic.co/support/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?
