lookup timeouts

[Ryan Permeh]

I'm having some trouble with our main nameserver:

the  setup:  solaris 2.6, bind 8.2.2p3, about 850 zones loaded locally,
allow-query is set to any.

the problem:
we have a single domain(it may be more, but no other domain has come to
out attention) that will time out on any query to our nameserver.  Our
secondary and tertiary nameservers can find this domain fine, but when
our primary does a lookup on it, it times out.  I have used ndc to
perform a named_db.db dump, and have found most of them right in the
cache part of the dump, including the SOA for the domain we are having
trouble with.
the weird part is this:  a complete shutdown and restart will allow
lookups for this domain to happen correctly for a while, but a HUP will
not.


Has anyone seen this happening?  Does anyone have any ideas on what
could be causing this?

I'd appreciate any pointers or ideas regarding this seemingly strange
behavior of bind.

Thanks a ton, Ryan Permeh, IS Engineer
