I've recently replaced the master server at 24.222.7.11, and am now running
bind 9.7.3.

My question is: I keep seeing log entries like

Apr 2 23:24:17 clementine named[5870]: lame server resolving
'comuna.silverorange.com' (in 'silverorange.com'?): 24.222.7.12#53
Apr 2 23:24:01 clementine named[5870]: lame server resolving 'veseys.com'
(in
'veseys.com'?): 24.222.7.12#53

and the list goes on. I don't get a lot, probably a few a minute. But where
do
they come from?

Does the following help:

ns3.silverorange.com seems to be down, and the other two nameservers being

Since the log message is specifically about ns1, how could ns3's status
be relevant?

listed aren't responding to TCP port 53.

Why would clementine be trying TCP?  His server appears to support
EDNS0, so it shouldn't need it.

I'm not saying this isn't a problem, but I don't think it would cause
this symptom.


@Chuck: I've sorted out the TCP issue with ns2. I'm not sure why the tests are failing for ns3, though. I can dig successfully on it from a variety of networks, using both TCP and UDP. I re-ran the tests, and ns1 seems to check out.

@Barry: The previous sysadmin set some of our NS entries on some of our domains in no particular order. As a result, some of the domains list the master (ns1.silverorange.com) as the second or third entry. Not sure if that matters. I'm correcting that now, and will know if that makes a difference a little later.
