About 8 days ago, my ADSL modem lost connection to the world for a bit, and then regained it. dhcpcd (6.11.3 from pkgsrc) all the while furiously re-tried to regain a lease, but when it did, named (from NetBSD 7.0.1) was broken:

When I noticed them and restarted named, they went away. Why does named not succeed in using the interface when it gets an address again? What to do about it? I noticed partly because my dns data seemed to have dropped out of caching name servers elsewhere. -Olaf. -- ___ Olaf 'Rhialto' Seibert -- Wayland: Those who don't understand X \X/ rhialto/at/xs4all.nl -- are condemned to reinvent it.
