Radius server unreachable events

vSZ version 5.2.0.0.699 with 411 R710s APs on campus. Every few days we are getting a bunch of radius server unreachable events. What is odd is the details of the event do not even point to our radius server. All events are reported like this

AP [Int301@F8:E7:1E:2A:A4:40] is unable to reach radius server [127.0.0.1].

Of course 127.0.0.1 is not our radius server. We are using Cloudpath as our radius server. Our wifi is rock solid so there are no other symptoms other than a rash of these events every few days.

Any ideas what causes this?
