We have two sites that are linked via two AP 60s with external aerials. These AP's have been setup as a mesh in order to extend the site to another building.
This has been up and running for the past 3 years but now the link between the two sites keeps dropping
When I look at the logs we keep seeing
Oct 9 05:08:55 nanny[139]: <303022> <WARN> |AP Start_Hill_AP@10.233.82.202 nanny| Reboot Reason: AP rebooted Tue Oct 9 14:07:08 BST 2012: SAPD: Unable to contact switch. Called by sapd_keepalive_cb:4462

The Start_Hill AP is connected directly to the controller so we can't understand why it keeps rebooting.
They are running software version 3.4.0.4
Can anyone suggest anything?
