Resetting a processing unit

Section 1.3 served, in the context of the discussion on persistence and integrity, to bring the issue of the necessity, or not, of having a fallback state. 

In the case of an integrity system, the transition to a fallback state is final. Within the context of a transient defect, the unavailability induced may be unacceptable from the viewpoint of the client (for example, loss of the anti-lock breaking system (ABS) function in a car). Therefore, it is tempting to go through an intermediate 

which attempts to reset all or part (one processing unit among n) of the equipment. 

Use of the reset function must be controlled, several problems may appear 

Regarding the reset of equipment, attentiveness is key, and it must be shown that the measure is efficient and there is no risk of hiding an erroneous situation.
