Yes -- I've seen that on the one machine I've tried to update so far. ntpd crashes for me after freebsd-update(8). Anecdotal evidence is that rebooting apparently causes the updated ntpd to function normally. I'd be interested in hearing if people can confirm that, because it means there is system state somehow carrying over from one invocation of ntpd to another. There's a thread on freebsd-security@.... -- seems there's also a problem with the ntpq and ntpdc utilities.
