I have a setup with one virtual MM and 2 local mobility controllers (7205), in a cluster setup. (8.4.0.2_70086)
The setup expanded from 1 to 2 MC a few weeks ago, and all was working as it should. A few days ago, the MM, was telling me, that about 60 ap, was down out of 250 ap's. But my airwave, shows all online, and several with users on. I can ping the "offline" ap's.
The ap's gets back online, if i reboot them.
Where can i look, to solve this problem?
