Hello, and sorry for starting a new thread when the last one is from June - I subscribed only recently and the mail archive does not show mail ids. Anyway, I'm referring to the thread from Attila Nagy: "No answers from unbound occasionally" - we're seeing much the same symptoms (using 1.3.2), i.e. unbound sometimes not answering queries, and debugging is a pain - we're running a load-balanced setup with currently 3 unbound nodes, around 22k q/s, each unbound node doing ~6-8k qps. It usually works fast & fine, but some queries appear to get eaten - we're getting occasional dns resolution errors when using unbound as cache that we never got with our dnscache (djb) setup. I've debugged as far as seeing that the queries reach unbound (they get logged), but I don't know whether unbound answered and the packets got lost, or if unbound simply did not answer at all.
Any ideas on debugging this? "Occasionally" means a couple 100 queries per day (out of roughly 1.1G total queries). My "exceeded" (jostle) counter is 0, average number of waiting requests is <10 per hosts.
