pid_max값을 초과하면 발생하는 문제점

• PIDs are generated sequentially and before being assigned to a process a check is made to ensure a process doesn't currently have a particular PID. When pid_max is reached the counter simply wraps back to the beginning. If there are no more PIDs available then no more proceses can be created.
