IncompleteRead during paginated request?

I'm getting errors like the ones below in sporadic cases, and am at a loss as to how to get around it. 

 

My code is generating paginated requests and processing the responses.  My initial thought was that I could put in something like https://stackoverflow.com/questions/44378849/bypassing-the-incompleteread-exception to retry a certain number of times when it encounters such an exception, but my guess is that since the request is paginated (i.e. implementing the fix at https://community.infoblox.com/t5/API-Integration/Specify-max-records-for-a-query/m-p/12781#M1608), that the retry attempts would fail because the _page_id value wouldn't be valid anymore.   Has anyone else seen this or have any thoughts?

Can you post this portion of your code?

 

How many objects & pages & objects per page are you pulling?  And are you pulling all paged relatively quickly, or are they pulled one page at a time over a longer timeframe?

 

I'm wondering if some part of the data is expired or modified, before it can all be pulleds, thus expiring the dataset you are pulling.
