Elasticsearch dies after some time running perfectly fine, it leaves no entry in the elasticsearch error but there is JVM error which I uploaded here: [https://gist.github.com/ofrivera/ece25bbd7d451c85241ca45517b6b85d](https://gist.github.com/ofrivera/ece25bbd7d451c85241ca45517b6b85d)

Can you please clarify the version number, as there is no 6.4.2.1.
What OS are you on?
Can you upgrade the JVM?

You can see what we support here - [https://www.elastic.co/support/matrix#matrix\_jvm](https://www.elastic.co/support/matrix#matrix_jvm) - but we always recommend the latest.

I'm upgrading java using the latest version from here [https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html](https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)

Java(TM) SE Runtime Environment (build 1.8.0\_191-b12)

Will let it run for a few days and see how works out
