9800-CL WLC Repeated Client Exclusion for Wrong PSK

CARL90

I've recently inherited a 9800-CL WLC with a somewhat questionable configuration.  It seems to be working as expected, however reviewing the Syslog shows regular repeated errors.  The error in question is:

%CLIENT_EXCLUSION_SERVER-5-ADD_TO_EXCLUSIONLIST_REASON_DYNAMIC: Chassis 1 R0/0: wncmgrd: Client MAC: dcb5.XX was added to exclusion list associated with AP Name:AP013, BSSID:MAC: 84f1.XX, reason:Wrong PSK

I'm seeing these appear about once per minute or more.  The error is thrown repeatedly for the same device every few minutes it appears with a decent number of devices causing the error while on-site.  Oddly enough there haven't been any reported issues with disconnects or failure to connect.  From what I've found, based on the MAC address every device being reported is an Apple device, almost certainly to be an iPhone that is issued to users.  Is there any specific configuration that may have been misconfigured that might cause this issue?  Any ideas would be greatly appreciated.
