Only one instance of ntpd is supposed to be running.  Something about 
the way you are starting your system is starting two processes.  The 
most likely cause is executing the ntpd startup script twice.  If you add:
echo "Starting ntpd at `date`"
to the script that starts ntpd, you will see the message twice during 
startup if that is your problem.  I can't imagine what else it might be 
so, if it is something else, please let us know.
