Any idea on what this might be, or what to look for to figure it out?
Are you showing this type of activity? If so, welcome to the club!
It could be image leeching. It could also be that you have implemented a design change that uses more images per page, or an extra call to a script, include, stylesheet, or JS-file (or whatever).
If you're sure that you have not made design changes in this period, then look for non-GET requests - have you got a lot of linkcheckers HEAD-ing? Form-POST-ing?
If these are stable as well, i think you can assume the image leeching is taking place.
