net/ntp startup twice or more? in boot time.

Yes, I have 4 jails, but only one ntpd service at host.

The symptom matches starting two ntpd that bind to the same interfaces (or where IP address is wildcarded). That, coupled with observation of a very low pid (38) and very high pid (79840) made me think that the latter must have been started from a jail. I would double check what jails do.

This thread is years old, so my answer is not for the op, but for someone who came to this topic searching by the message "unable to bind to wildcard address".
I came across this problem and found that if ntpd once fails with this message, one process of ntpd remains and not be killed by service ntpd stop. I solved the problem by calling pkill ntpd first, then call service ntpd start.
