we use bind9.5.0-P2 for the internet dns server.
Sometimes we get no response for some domains, like this:
; <<>> DiG 9.3.2 <<>> cluster3.eu.messagelabs.com
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 34869
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0
;; QUESTION SECTION:
;cluster3.eu.messagelabs.com. IN A
;; Query time: 166 msec
;; SERVER: 220.127.116.11#53(18.104.22.168)
;; WHEN: Fri Aug 21 11:00:01 2009
;; MSG SIZE rcvd: 45
If we ask the same question a few seconds later, we get a correct
answer. ( e.g. two out-of ten we get an error)
Then we stop and start the named daemon and it works fine for a while.
How can we debug this issue?
Thanks in advance.
