SYMPTOMS
When re-authentication to a wireless access point is performed by using the Wi-Fi Protected Access-Protected Extensible Authentication Protocol (WPA-PEAP) authentication, memory may be permanently consumed. This problem may eventually lead to degradation of performance or system instability. Re-authentication may occur after access point requests on pre-configured intervals.
