E00003 Error sporadically happening since July 2

Receiving E00003 XML Parser Error on appx 1-3 transactions per day (see below). Most transactions go through fine. It started on July 2, seems to be random and we can't tie it to any changes or plug-in updates on our end. No issues before this date. Nothing changed on our end. Anyone have info that can help us fix this?
