A UIMVM device that has been placed in maintenance mode with a scheduled calendar window time, is automatically and unexpectedly taken out of maintenance by the System account, before the end of maintenance schedule time.

SetMaintenanceModeToChildren Attribute value "No" (By default the SetMaintenanceModeToChildren Attribute value "Yes" ) on OneClick -> UIMManger -> Attributes
