'Elasticsearch container keeps exiting with these logs

I have a docker container with elasticsearch in it. I think when too much requests is sent to my server this container crashes (exits). Could you approve that this is because of the pressure on server? As we see in logs:

Additional info: I have recently resized my server and made it bigger and faster, and now it doesn't exit anymore, but the question is still live.
