Hello,
   We routinely collect objects' data from our salesforce org via running SOQL querries using the API, authenticating via token and refresh token.  Starting 4/29/17 we started to see our connection being reset after a few batches of data (Log below).  We are able to collect this data from our staging server (even thought we still saw some of these errors), but for some reason our connection is always being reset on our production server.  The call that we usually see this error on is the authentication call to refresh our token.

Any ideas why we would be experiencing this error?

Thanks for the help!
