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:

a ticket with ISC, and they are looking into it. Can you share any addition=
al information that might aid troubleshooting?
If anyone else experiences this, please report it.
