When I am executing command on MongoDB CLI- db.table.find() 

there is no issue.

Now I have an application for retention in PyMongo.

Pymongo throws error after 167 records.

I have 13 columns in the document

I added indexes for all columns earlier it was on 10 columns and still it was throwing error. 

I increased MongoDB RAM size.

I increased time to 60000 milli seconds.

Error didnot resolved yet.

I have MongoDB 4.2 version and PyMongo 3.10.1 version
