Bind Logging

When you say (as you did in your earlier message) "no nslookup", do you mean
that nslookup just hangs? Does it eventually time out? The stats below would
indicate that the nameserver is functioning normally, but it's conceivable that
when nslookup tries to reverse-resolve the nameserver address, named might need
to talk to other nameservers to resolve it, and if they are down, unavailable,
or just plain busy, then nslookup could take a long time to respond.
