Elasticsearch 6.4.2 crashes after some time running perfectly fine

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

This how my config looks like:
cluster.name: media-es
node.name: media04
network.host: media04.my.net
http.port: 9200
discovery.zen.ping.unicast.hosts: [media01.my.net,media02.my.net,media03.my.net,media05.my.net]
discovery.zen.minimum_master_nodes: 2
path.data: /elasticsearch/data
path.logs: /var/log/elasticsearch
node.master: true
node.data: true

reindex.remote.whitelist: media.my.net:9200
path.repo: ["/mnt/snapshot"]
xpack.security.enabled: false


5 nodes: 2 routing 3 data
16gb RAM memory

Can you please clarify the version number, as there is no

What OS are you on?
Can you upgrade the JVM?

sure thanks for the quick reply!

java version "1.8.0_92"
Java(TM) SE Runtime Environment (build 1.8.0_92-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)

I will try to find whats available in terms of updates for my java version. Is there any recommended version?

You can see what we support here - 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

java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)

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