Can you say `packet storm'? I knew you could ... All our servers here run local nameservers, and only have secondary nameserver entries listed for the rare occasions named core dumps. I don't want to go increasing the ammount of UDP traffic on to my backup nameservers by a factor of 50 (if not more). Even switched fastether can only take so much. Seems your problem is not the resolver, but your nameserver setup. My guess is problems arise from doing lookups on `internal' addresses on `external' nameservers? The correct solution then is to run a nameserver on the firewall, and force it to bind only to 127.0.0.1. You use that in your resolv.conf, and teach it enough about the topology to answer properly.
