I am trying to push 80mb document to elasticsearch cluster and getting "Error while copying content to a stream".

I have also increase heap size as -Xms6g, -Xmx6g still getting an error.

It's quite hard to read your question because it is poorly-formatted, and poorly-formatted posts often don't get a useful response. Please format logs etc. using the `</>` button to make it easier to read, and check the preview of your post before sending it to make sure it looks ok.

As far as I can see you've only provided client-side logs, which basically say that the server shut the connection down. The server logs ought to contain more information about why this happened.

I am trying to push the 80mb document to ElasticSearch cluster and getting "Error while copying content to a stream".

FYI, The **Used HEAP** sized readched at 99%.

**Additional Information**

We have developed the .NetCore WebApi Application using **NEST** library for CRUD (Create, read, update, delete) Operation in ElasticSearch.  
We have setup ElasticSearch with Ingest plug-in on kubernetes cluster with HeapSize 2gb (On cloud).

Goal: Add 100,000 documents (Per Document Size: 13MB to 15MB) in ElasticSearch in 10 - 15 Minutes

Could you please suggest the ideal ElasticSearch configuration or ElasticSearch configuration for high performance for the above requirement.

Thanks in Advanced.

You need to look at the server logs.
