Colleagues,

Upgraded to ntpd 4.2.7p303 from p295 two days ago and twice now it has
died unexpected with the following error:

12 Sep 23:40:26 ntpd[83434]: 86.47.187.7 local addr 172.16.2.10 -> <null>
12 Sep 23:40:48 ntpd[83434]: ntp_monitor.c:136: ENSURE(punlinked ==
mon) failed
12 Sep 23:40:48 ntpd[83434]: exiting (due to assertion failure)

Startup seems to be optimal:

This has only happened since I have upgraded from p295 three days ago.
P295 was not experiencing this difficulty.

My platform is FreeBSD-8.3, and this port is ntp-devel.

Suggestions for the cause?

Thanks,

Ron
