I Had the same problem with a MSM760 and 135 AP MSM310. I have 1 MSM560 and 1 MSM430 also.
Thurough the MSM760 console there no way to do schedule resets.
I made two schedule scripts in the Windows 2008 System using plink and ssh console.
The first scritp does a reset to factory defaults for each AP and the second one does the accept command for the same APs in the first one. This scripts runs CLI commands for this operations.
I was running firmware version 6.0, some of the APs went to radio status pending and high CPU when the number of users and wlan traffic increase during the operation time. So whe had to reset the APs to have a fresh start.
I did this two times a week.
