AP Impersonation of MAC

Occasionally WCS will throw the following error:

   AP Impersonation of MAC 'Redacted' using source MAC  'Redacted' is detected by authenticated AP 'Redacted' on  '802.11b/g' radio and Slot ID '0'.

We are running version 7.0.172.0  and the only thing I can find about this error indicated that I should check the controller. When I look on the controller I do not see the error in the syslog. Does anyone have an idea of what could be causing this error?
