So my two node cluster is constantly restarting due to running out of memory, and its happening in a testing environment, with at most 10 users writing to and searching the database.

And now the error reads that all shards have failed, and I get an internal server error of 500 when trying to access Kibana from the console.

We are running 5.2.0, this was a 1 gb memory cluster with two nodes.
