@manoranjan if you restart Kibana, does it start working again? ---

I think it has to do with heap size: my total Heap size is 784 MB and Heap used is 772.67, I have read some where that we should reduce the use of field data and use doc values instead. Can you guide me how to do that as I am kinda new to ES. ---

@manoranjan I'd recommend moving this topic over to the Elasticsearch forum, as there will be a lot more knowledgeable people over there who can help you with this. ---
