The info says - it's named, so not what you have been seeing:

Oct 22 19:23:02 quartz syslogd: Exiting on signal 15

rebooting...

This happened with today's cvs, while shutting down.  I remember
restarting named when I had the freeze mentioned in the original
email, but also had a build going at the same time, so it wasn't
obviously the named restart...
