9.6 Constant wifi channel errors

We've been seeing a constant stream of errors in the wireless logs of one of our pair of SG 115s with 3 AP55s attached.  We have 20+ of these same setups at other locations that do not display these same errors, running on different firmware revisions.

 

Currently, with the firmware at 9.602-3, our wireless log shows this constantly:

Support told us this error is benign, but we've have frequent reports of dropped wifi / packet loss at this site and I'm not willing to discount it out of hand.  Anyone else seen this?  Or can anyone provide insight into resolving it?
