We have recently begun seeing a large volume of "Malformed Frame - Large Duration" messages on our M3 running 220.127.116.11. This seems to only occur at certain times (mostly late afternoon & overnight). When I see these messages they appear to be from APs all over campus - even a geographically seperated remote site. On the latest look, my own Macbook was logged as one of the devices.
Any idea what could be causing this?
