Hi,

I am running on ES-5.0.0 .  
It works for a while but then it stops.  
When I restart ES it is running. However again it stops after a while  
During that time I was doing a bulk index.

What is the problem?

Likely OOM killer or something similar due to resource pressure if it's during a bulk load. Check the error logs:

/var/log/elasticsearch/elasticsearch.log  
/var/log/messages

(assuming you're using Linux and the defaults here).
