I'm running two 5520 WLC in a HA-cluster in a centrally network architecture. The controller is running firmware version 8.2.101.0 and the AP's are running in FlexConnect mode (AIR-AP1832I-E-K9) on different branch offices. At random times the country codes of different AP's are changed to (AT) and the admin status of the AP is disabled. Furthermore there are some AP's connected to this controller what are not located in Europe. These AP's have a 'B' model and it seems those AP's are not effected by this issue.
The below lines are found in the syslog (read down-2-up):

Does anyone has an idea what is causing this country code change and the AP disabling?
