Hi,
PowerDNS Auth Server 4.3.0 with PostgreSQL backend I'm facing the fact, that sometimes the servfail-packets counter increases and i would debug this and find the reason why PowerDNS sends out a "servfail" packet. Actually today the counter increased from 0 to 2 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? I noticed this behaviour for a long time and over different versions (4.1, and 4.2). Last time i asked, there was no answer: https://mailman.powerdns.com/pipermail/pdns-users/2019-February/025767.html Thanks! Regards MK
