I have 3 node cluster, deployed in AWS. The elastic service going down now and then with following exception. I am using 3 node(each of 3 node acting as data, master, ingest).

node2, node3 was down and node1 was up looking for other master to join the cluster. So whole cluster is down. I took backup the logs from node2 and node3. ---

Based on the stats you provided, it seems like you have set the heap \> 50% of available RAM. I would recommend changing this to give Elasticsearch enough file system cache to work with. I have also never deployed Elasticsearch on t2 instance types, so am not sure how suitable they are due to the burstable performance. I think it is much more common to use m4/m5 instances, so it might be worthwhile switching to see if that helps. ---

Thanks, I will change it to M4.xlarge. It has 16GB memory. How much you suggest to give elasticsearch? I gave 14 GB with previous configuration. ---

Christian, I have upgraded to M4.xlarge and assigned 8 GB memory. Now cluster looks stable(Thanks for that 🙂 ). I am getting following warning. From console I can see incense expires March 4, 2018. Our Prod subscription will start from 14th Feb.
