table capacity is limited and the number of process numbers available is limited, if a large number of zombie processes are generated, The system cannot produce a new process because no process number is available.Therefore, the defunct process not only consumes the memory resources of the system, affects the performance of the system, but also causes the system to be paralyzed if its number is too large. Also, because the scheduler cannot select the defunct process, the defunct process cannot
