Have some new information now. These errors seems to have gone away on their own on our load-balanced service; however, the five eduroam (non-load balanced service) errors over the past few weeks are all for umn.edu logins so it's highly likely that this is a problem with the umn.edu eduroam server. We have users from many organizations using eduroam and only that org's logins are failing occasionally.

There's one idea you could try based on the quote of the above article:
Add on top level Radiator configuration this flag:
In case the client gets handled by another AP/controller during the
authentication and this causes the RADIUS message attributes to change,
this could cause problems keeping track of current authentications.
The above flag changes the tracking to use State attribute which could
help. If you use AuthBy EAPBALANCE, see the reference manual, because
it's likely to cause compatibility problems:
This option has been available for a while now and it seems to be
working fine. It's likely something that could be a default in the
