Host lookups fail at first, but then succeed consistently.


K, recently the newsletter I send has gone from taking 2 hours, to 24hours to send. I recently updated my bind to fix a buffer overflow (bind 9.1) and I figured I would test it to make sure it was working okay. Well when i run a "host whatever.com" it consistently fails on the first try, and then if I do it right after it works. The errors are:

;; connection timed out; no servers could be reached

There are no errors in my logs, and I have tried with numerous different sites with the same result. My box is hosted, so Iam wondering if the host is screwing up net traffic, but I am trying to narrow it down a little more before I accuse them of network issues. I have rebooted the server, and it didn't help, there is no abnormal traffic on my system. System specs are:

1.6ghz
512mb ram
Multi DC3 network
RH 7.2
Bind 9.2.1-1.7x.2

Any help or ideas are greatly appreciated. I don't see how it could be on my end.

TIA!
Mike..

It's relatively common for DNS to time out on the first try. A cacheing name server is likely taking too long to forward a dns request, and by the time it recieves the answer - your local already gave up. The subsequent request will have the cached answer. There are ways around this, but some info is required...

Post your named.conf - and the output of 'dig' for a "new" host.

dig ice.support.corvu.com

This will search DNS for one of my servers (Mandrake) - and will likely give enough output that we will be able to figure it out.
