It happens when a threaded program has (some) stacks swapped out. Named
is one of the few threaded programs in base (if not the only).

This should have worked. Sometimes (depending on kernel state) the dump
process itself stops, typical scenarios are lockmgr problems and
resource shortage (http://www.netbsd.org/cgi-bin/query-pr-single.pl?number=27135).

But if the dump succeeds, savecore should pick it up properly (unless you
have "savecore=NO" in /etc/rc.conf).
