Hi, I've been scratching my head for a few days now, trying to figure out what is happening here. 1) I noticed that the requestlist dump contains about 200 subdomains for groupinfra.com, some of them are there for up to 85000 seconds.
2) 1 entry in the requestlist is: 215 A IN xjdjtallrd.groupinfra.com. 25205.720826 iterator wants A IN de-dc002.groupinfra.com. A IN in-dc007.groupinfra.com. A IN uk-dc015.groupinfra.com. Resolving this domain with dig returns: # dig @localhost xjdjtallrd.groupinfra.com ; <<>> DiG 9.4.2-P2 <<>> @localhost xjdjtallrd.groupinfra.com ; (1 server found) ;; global options: printcmd ;; connection timed out; no servers could be reached # 3) flushing the requestlist and name from the cache # dig @localhost xjdjtallrd.groupinfra.com ; <<>> DiG 9.4.2-P2 <<>> @localhost xjdjtallrd.groupinfra.com ; (2 servers found) ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 65121 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; QUESTION SECTION: ;xjdjtallrd.groupinfra.com.

Flushing the requestlist and domain groupinfra.com from cache fixes again this issue. I am using unbound 1.4.7 on OpenBSD 4.5. Compile options: ./configure --prefix=/opt/unbound-1.4.7 \ --with-ssl=/usr \ --with-libevent=/usr \ --without-pthreads \ --with-chroot-dir=/var/unbound \ --with-pidfile=/var/run/unbound.pid \ --with-conf-file=/var/unbound/etc/unbound.conf \ --with-username=named \ --disable-gost \ --with-ldns-builtin I'm trying to understand why this domain is only temporaribly resolvable and after it fails, it is resolvable again after a flush of requestlist and domain groupinfra.com.
