I am running bind-9.7.2-P3, and I am having a problem with BIND or

but
dig produces a timeout message.
If you use dig to query the remote server directly (dig
@<other_server> foo) do you see the same issue?
One obvious thing to check would be if you have something like
iptables blocking the reply (tshark / tcpdump will still see the
packet).
Can I set some trace level to see if
the reply packet is being seen by BIND? And I am not sure into which
logging category the trace records would be written. Thanks.

I believe this will do sometihng helpful:
channel debug_log {
// Attach this channel for debugging messages..
file "/var/named/data/debug.log" size 1m versions 5;
severity debug;
print-category yes;
print-severity yes;
print-time yes;
};
category queries { debug_log; audit_log; };
