Go to the nas probe's Raw Configure GUI, select the setup folder from the left-hand pane, then Modify/Add the following key value in the right-hand pane:
maint_max_resp_time = 50
As stated in an earlier update, if you are not adding/modifying maintenance schedules on a frequent basis, then you can also modify the following key value from the nas probe's Raw Configure GUI:
registrationIntervalLookAheadMinutes = 60
This key determines how often the nas will attempt to re-register with the maintenance_mode probe. This key is set to 30 minutes by default, but if you have a large number of active schedules defined which do not get changed frequently, then you can increase the re-registration interval as well to 60 and even 90 minutes.
