records not being cached...

[Steve Foster]

hi there,

i have an issue with a bind9.2.1 resolver, i have a domain mediaproduct.fr
that will not get cached by this server until i restart the named process..
the resolver can resolver the "fr" domain and give me SOA records. e.g

> set type=soa
> mediaproduct.fr
Server:         localhost
Address:        127.0.0.1#53

** server can't find mediaproduct.fr: SERVFAIL
> fr    
Server:         localhost
Address:        127.0.0.1#53

Non-authoritative answer:
fr
        origin = ns1.nic.fr
        mail addr = nic.nic.fr
        serial = 2002111200
        refresh = 21600
        retry = 3600
        expire = 3600000
        minimum = 86400

Authoritative answers can be found from:
fr      nameserver = NS3.DOMAIN-REGISTRY.NL.
fr      nameserver = NS-EXT.VIX.COM.
fr      nameserver = DNS.CS.WISC.EDU.
fr      nameserver = DNS.INRIA.fr.
fr      nameserver = DNS.PRINCETON.EDU.
fr      nameserver = ns1.nic.fr.
fr      nameserver = NS2.nic.fr.
fr      nameserver = NS3.nic.fr.
> mediaproduct.fr
Server:         localhost
Address:        127.0.0.1#53

** server can't find mediaproduct.fr: SERVFAIL

Could this be linked to the fact that none of the FR nameservers have an
SOA record for this domain, all they have is NS records and potentially the
first server i ask from the resolvers doesn't have any SOA information to
give..., except for dns.cs.wisc.edu, see below:
