In database production, the log of listener was grow rapidly, some times if you move the "listener.log" while the listener is up and running, listener will stop writing to log file after you move/delete the "listener.log", it won't create new log file.
The listener log status will be 'off', You need to start the "listener log" again manually. For this reason you must do this procedure.

bash> lsnrctl stat
