Radius EAP Error

Are there any Radius userers out there that has seen this error while running AAA in debug mode?  The users getting this error just keeps trying to authenticate, mean while the reg and rereg counts are going thru the roof.   The AP's and SM's are both PMP 450 3.65 Ghz with 14.2.1 firmware.
