It MIGHT be useful if we also had API logging....API logging would tell us definitively if it was Mid-Tier doing the call (which is what it looks like)...but it would also tell you the source IP of the machine making the call....I have never seen this behavior before but I suspect it might be related to caching somehow....once you know which of your mid-tier servers is causing it you can shut it down to verify that it stops when it's not running, and maybe do a hard cache flush to try and clean up whatever might be wonky.
