title: Elasticsearch stops working suddenly
body: <p>I am running Elasticsearch on a VPS and it was working perfectly for me. Initially, there were many rows indexed using Elasticsearch. When i tried to create new index, Elasticsearch stopped working. Now whenever i try to start Elasticsearch, it works for some time and then it gives me message "Killed" and it stops working. I deleted the new index that i had created and tried  to start Elasticsearch but it still gives me the same error. Any solutions to resolve this issue?</p>
