tried that as well... but no luck.. can u tell y this error is coming?
is it related to any config error???

i got this update

ntp 9763 1 0 23:11 ? 00:00:00 ntpd -u ntp:ntp -p /var/run/ntpd.pid -g
root 9766 9763 0 23:11 ? 00:00:00 ntpd -u ntp:ntp -p /var/run/ntpd.pid -g
ntp 10135 10132 0 23:15 ? 00:00:00 /usr/sbin/ntpd -q -u ntp:ntp
root 10154 10135 0 23:15 ? 00:00:00 /usr/sbin/ntpd -q -u ntp:ntp

It looks like some app is already using udp port 123 on your machine. Just check whether another instance of ntpd is already running on your system. You can also run the following command:
# netstat -n -f inet |grep 123
to find out the application that is using port 123

hi

when am issuing /etc/init.d/ntpd stop , the ntpd stops and when am issuing /etc/init.d/ntpd start .it starts with both
"ntp" user as well as "root" can you tell y this is happening?

ntp 9763 1 0 23:11 ? 00:00:00 ntpd -u ntp:ntp -p /var/run/ntpd.pid -g
root 9766 9763 0 23:11 ? 00:00:00 ntpd -u ntp:ntp -p /var/run/ntpd.pid -g
