Aug 31, 2017 at 18:33 comment added Rui F Ribeiro btw, which distro?
Aug 30, 2017 at 18:22 comment added Rui F Ribeiro It might still bit you in a contigency though. Maybe generating requests in one test server?
Aug 30, 2017 at 16:53 comment added David King that was supposed to be 'tripled' not 'tripped' :)
Aug 30, 2017 at 16:15 comment added David King Since I tripped the number of servers answering requests I haven't had any complaints which would seem to suggest it was hitting some kind of limit. I'm reluctant to cut back on servers just to test if this solves it because if it doesn't then I've subjected my people to bad Internet just to test a theory. I'm going to to with 1) it hasn't broken anything and 2) it's probably good practice to include and leave it at that. Thanks
Aug 29, 2017 at 14:53 comment added Rui F Ribeiro Let me know if it worked, I might have a couple extra tips to add to the answer.
Aug 29, 2017 at 14:43 comment added David King Interesting. That never showed up in my logs (I've long since deleted them but something about rate limiting would have been a massive red flag). Thanks for the tip. I'll give it a shot
Aug 29, 2017 at 14:04 comment added Rui F Ribeiro under options recursive-clients 30000; for instance - that was one of my biggest rookie mistakes when I started using BIND in an ISP setting ; I think you are hitting the built-in limit of 1000. The details are fuzzy in my mind, but you ought to have logs about that.
Aug 29, 2017 at 13:52 comment added David King I'm not entirely sure what you mean by the number of default clients. I can't find a client limit anywhere in the documentation. I've edited the question to include my named.conf if it's helpful.

added named.conf
Aug 28, 2017 at 18:24 comment added Rui F Ribeiro (i also have high logging, but that is an entirely different talk. BIND ought to be simple, had many servers and never had issues I could not solve) Are you sure it is not firewall or infra-structure limitations?
Aug 28, 2017 at 12:48 comment added Rui F Ribeiro Hmmm odd. Have you raised the number of default clients?
Aug 28, 2017 at 12:24 comment added David King Not really. I discovered that having logging turned up too much (like you would have it when you're having problems) can cause problems for Bind. I turned logging off and tripled the number of servers handling those requests. It's better now but I don't think I really solved the ultimate issue.
Aug 25, 2017 at 22:00 comment added Rui F Ribeiro Have you managed to fix this?
