hi, pdns auth server 4.1.6 with postgresql backend
i'm facing the fact, that from time to time the servfail-packets counter increases, and i don't know, why. https://doc.powerdns.com/authoritative/performance.html#servfail-packets tells me, that this is due to a database problem. https://doc.powerdns.com/authoritative/performance.html#ring-buffers tells me that the servfail-queries ring-buffer shows which queries have been causing servfails. but when i look at this ring-buffer (server:8081/?ring=servfail-queries) there are no entries - it's empty. can someone please explain, what am i missing or not understanding correctly? the amount of servfail packets is really low - 14 servfail on 2 mio queries, but it is really annoing, since i don't know, what's going on... how can i debug, what query causes a servfail? Thanks in advance. regards MK
