I'm running a few BIND servers, but lately one of my servers suddenly starts responding to clients with servfail for every request from the clients, and BIND doesn't respond to the rndc or statistics interface anymore.
My logs for client-channel show me this:
25-Apr-2020 21:52:04.501 client @XX XX.37#2921 (google.dk): no more
recursive clients (1000/900/1000): quota reached
I've removed all the dns traffic from the server, and the quota is still reached after 6+ hours?
Do you guys have some clue what all this is about? - Or any suggestions
where to look for any further information?
I'm running BIND 9.16.1 on CentOS 7:
I've had the very same thing happen twice in the past two weeks on different production recursive servers running BIND 9.16.2 on FreeBSD. I've opened a ticket with ISC, and they are looking into it. Can you share any additional information that might aid troubleshooting?
If anyone else experiences this, please report it.
