AP keeps dropping from WLAN Controller

I have some problems with 1242 APs dropping from 4400 WLAN Controller. The cause it says is a 'Heartbeat Timeout'. I haven't upgraded or changed settings on WLC or AP. Any ideas what might cause this and how I can fix it?

Are you, by any chance, running H-REAP?

No, we are tunneling all the traffic back to our controller. We have 8 Mesh AP that talk to 4 Root AP.

Go to Wirelss > Access Point > Global Configuration. Look for "Local Mode AP Fast Heartbeat Timer State" and make sure it's Disabled.
