Similar to failstop, but it also concedes that the stopping may not be instantaneous and that stopping quickly may be good enough. Sometimes, watchdog timers are employed as a mechanism to achieve failfast behavior.
In practice, a component should be internally checking its own correct operation; upon detecting an error in itself, it should stop its execution before it has a chance to corrupt data or propagate errors to other components outside itself. The concept that a component either executes completely correctly or it halts.
Closely related to failstop and fault containment. A method to ensure that a faulty component cannot propagate errors or failure. Surviving components prevent the defective component from accessing other components or data.
A defect, but possibly an imprecise error.
A method to prevent a failed component from propagating to other components.
A method to determine the source of a fault and the component or FRU that requires repair.
A division of a system in which a set of disjointed zones facilitates fault isolation.
Transmission of a fault to unaffected areas of the system.
An area of the system in which recovery work is performed on a component in that area.
