You have some other program already running on port 123.  Perhaps another
instance of nptd?  Try "sockstat -4 | grep 123" and see what comes up.

This is not specifically a jail problem, but it could be that you
accidentally configured one of your jails to start ntpd as well.  This
is unnecessary.  Each jail will get it's time from the host, so it's
only necessary to sync the host.
