Hi,
I *think* I've seen this behaviour in some of our Raqs here, but what I
ended up trying seemed to cure it.
Out of interest have the machines been rebooted recently, or simply not
ever had bind/named restarted manually??
For some reason after a reboot our machines will start the
/usr/sbin/named process but it won't answer queries in the way that you
explain.
If I ssh in and call a
/etc/rc.d/init.d/named restart
Give it a minute to settle down, and hey presto it starts to answer
again, and will continue to do so after that point.

I've never tracked down the fault (anyone? I'm open to suggestions) but
that seemed to get it working at least.

Not ideal, but I'm interested if it helps your problems in this case.
