To kill a port monitor, use the following command:
sacadm -k -p pmtag
(The SAC daemon sends a SIGTERM signal to pmtag.) The state STOPPING is an intermediate state on the way to the NOTRUNNING state -- the port monitor has been manually terminated but has not completed its shutdown procedure. The state NOTRUNNING means the port monitor is not currently running. This is the normal ``not running'' state. When a port monitor is killed, all ports it was monitoring are inaccessible. It is not possible for an external user to tell whether a port is not being monitored or the system is down. If the port monitor is not killed but is in the DISABLED state, it may be possible (depending on the port monitor being used) to write a message on the inaccessible port telling the user who is trying to access the port that it is disabled. This is the advantage of having the DISABLED state as well as the NOTRUNNING state.
