Sorry, I forgot to mention that this is an authoritative nameserver. (For several ccTLDs. Each customers has its own Bind process. Currently I only noticed timeouts on Binds hosting bigger ccTLDs).
I will look how to integrate eu-stack into our monitoring check.

Anything unusual like RPZ or catz? Try snapshoting the call stack with eu-stack and save the one when the timeout happens.

On our production name servers we have check every 30s if bind is alive by sending a SOA query to bind. Today I upgraded a few nodes from 9.18.x (x between 17 and 27) to 9.20.1 (Ubuntu 24.04 with packages from ISC ppa). Since that, we have sporadic timeouts (3s). On the nodes with more qps we see it more often. Before I dig into the problem, are there any specific changes to 9.20 that I should look at? Maybe some default value changes for socket buffers, thread handling …?
