this has happened to me a couple times with named 8.2.3 on my 1.4.x
system. most recently was a couple days ago, in fact.
I have a theory that it gets worse when you have a really good
forwarder. since you are seldom talking to the root nameservers, the
TTL for the root name servers expires. then when your forwarder fails
and you _do_ need to talk to the root name servers, you don't know who
or where they are; hence the error message.
if I understand correctly, the root hints file is only consulted on
startup to prime the root zone -- once named is up and running, the file
is never again referenced.
I'm not sure of the correct solution.
