multiple named process in a single machine?

Your problem is not with port 53. Note that it states it is having
trouble binding a TCP socket, so even if it was port 53 your query would
have worked on UDP port 53. Zone transfers would not have though...
Anyway, port 953 is bound to loopback and that is why you are getting
the address in use message. The named process listens on this port for
rndc (remote ndc) commands. You will either need to change the IP in the
controls section of each named.conf (which means using rndc as a true
remote control mechanism) or by changing the port for one of the servers
(which means modifying the port that the rndc commands uses every time
you want to manage that server). My recommendation is that you use the
first... Hope this helps!

Subject: multiple named process in a single machine?
Hello,
Since named seems do not scale well on 4+ CPUs, I plan to use multi
named process in a single machine with multi IPs.
I managed started named process with different named.conf files, and
limit IP address for each with 'listen-on' option in named.conf.
But from syslog, a message said:
listening on IPv4 interface eth0, 10.101.0.88#53
binding TCP socket: address in use
couldn't add command channel 127.0.0.1#953: address in use
couldn't add command channel ::1#953: address in use
zone xxx/IN: loaded serial 42
running
I tried dig from clients to different server IPs, it just work!
Anybody can tell me does this make sense? If yes how to eliminate
the 'addr in use' errors in syslog?
Thx.
