Description (partial)

Symptom:
An access point may unexpected reload every four hours.

Conditions:
Seen with AP-COS access points (all models) - not with IOS APs.
Seen if running version 8_10_112_0 or 8_10_121_0 - not seen with earlier code.
AP has good connectivity in CAPWAP to its controller - however, there exists an ACL in the network, between the AP and its default gateway, that blocks ICMP.
