Converged architecture : when the mob Controller goes down, all AP connected to Mob. Agent are disconnected

Question

Hello
I configured two  SW 3650 in a converged architecture.
SW3560-1 is Mob controller
SW3560-2 is Mob agent.
When I shut down the Mob controller, APs associated to the Mob. Agent reload, and could not join anymore to the Mob Agent.
A debug "capawap ap error" on sw3560-2 give this error:
"*Sep  5 07:51:52.144: *%LWAPP-3-AP_LICENSE_REQUEST_ERR: 1 wcm:  License request failed for AP 7c0e.ceb8.f5d0 - AP License Request timedout, ensure MC link is up, Resettting AP"
Both SW3560 has a valid license for 6 AP
So I guess that the Mob Ctrl in a converged architecture, is vital.There is no redundance.
Could you please help.

Hi Michel,
When I shut down the Mob controller, APs associated to the Mob. Agent reload, and could not join anymore to the Mob Agent.
When MC is down, if MA connected AP rebooted that is strange. As Sultha mentioned, without MC, AP won't able to register as AP licence hold on MC.
Where is the SVI defined for AP management vlan ? Is DHCP given for AP from 3650-1 ? We need to find out what triggers MA connected AP to reboot.
Configuring both 3650 as MC is not an ideal solution (make it bit complex & roaming is not optimized if these two switches in same building)
