Description (partial)

Symptom:
Wireless users on a particular channel will find themselves unable, or barely able, to communicate.  Channel duty cycle is seen to be near 100%.  OTA capture finds that an AP is sending RTS frames to a client at ~ 8000pps, which client is no longer active.

This RTS flood will persist for about one hour.

Conditions:
The wireless client to whom the AP is sending the RTS flood is no longer there.  It had been in the middle of a large data transfer when it shut down (or disabled its interface, or left the building.)

The WLAN is set with a high user idle timeout value, one hour or longer.
