We've recently deployed around 200 AP103H units, which are generally working really well but I've noticed we've had a couple of occasions when a unit appears to crash. They drop off the controller and don't respond to ping, but the switch port is still up. Left alone the AP doesn't come back up. The switch reports the port going up and down from the point the AP drops off, which looks like the AP rebooting. As soon as I power cycle the POE on the switch port and it then comes back. When this happens it's one AP out of maybe 30 in the building, all on the same switch. The switch is an HP2920.
Anybody else seen this kind of behaviour?
