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!

Over the past week, I've been getting intermittent "Connection reset by peer" errors while querying contacts.

2004-04-13 15:44:13,968 INFO  CaIntegration.CaIntegration cleanup (CaIntegration.java:137) - Connection to sforce closed

 

The line which throws this exception is:

                sobjects = binding.retrieve(fieldList, entityName, idList);

Similiar queries to account doesn't result in any issues. I'm using Java 1.3 (for deployment compliance reasons) with SOAP API 2.5.

 

Has anyone else seen this?
