Description (partial)

Symptom:
FPR-1010 appliances (running ASA software) operating constantly at a fairly high CPU temperature around 75-76 C. Since it appears that 76 C is the threshold for "Warm" rather than "OK" temperature, we are getting repeated log messages like:
%ASA-4-735015: CPU 0: Temp: 76 C, Warm
%ASA-1-735020: CPU 0: Temp: 75 C, OK
as the appliance bounces back and forth between 75 and 76 C.
