Mobicontrol admin : strange behavior ...
When was the last time the services were restarted? You may want to reboot the server if you’re seeing strange behavior like that.
Have you upgraded your MobiControl server, device agent or device firmware recently?
Have you checked the DS and DSE log file for any warning/error messages related to scheduled or manually initiated profile deployment. You might need to change the log levels to verbose to get more information.
How many profiles are targeted to your problematic device? Do all or just one profile fail to be deployed? Is the failing pattern exactly the same for your 700+ devices of the same model/firmware-version?
Check if there are any rules within filter criteria when you assigning the profiles.
