Do resource malfunctions that render a resource unusable generally increase or decrease the likelihood of deadlocks and indefinite postponement? Explain your answer.
What will be an ideal response?
They would tend to increase the likelihood of deadlocks and indefinite postponement. In a Banker’s-Algorithm deadlock avoidance scheme, this might have the effect of making a previously safe state unsafe. In Havender’s linear ordering, it might have the effect of removing a resource that a process already holding resources needs in order to proceed. The likelihood of indefinite postponement increases in priority-based allocation schemes for low- priority processes.
