<div>Hi,</div>
<div> </div>
<div>I've been scratching my head for a few days now, trying to figure out what is happening here.</div>
<div>1) I noticed that the requestlist dump contains about 200 subdomains for groupinfra.com, some of them are there for up to 85000 seconds.</div>
<div> </div>
<div>2) 1 entry in the requestlist is:</div>
<div>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.</div>
<div> </div>
<div>Resolving this domain with dig returns:</div>
<div> </div>
<div># dig @localhost xjdjtallrd.groupinfra.com </div>
<div> </div>
<div>; <<>> DiG 9.4.2-P2 <<>> @localhost xjdjtallrd.groupinfra.com</div>
<div>; (1 server found)</div>
<div>;; global options: printcmd</div>
<div>;; connection timed out; no servers could be reached</div>
<div># </div>
<div> </div>
<div>3) flushing the requestlist and name from the cache </div>
<div> </div>
<div># dig @localhost xjdjtallrd.groupinfra.com </div>
<div> </div>
<div>; <<>> DiG 9.4.2-P2 <<>> @localhost xjdjtallrd.groupinfra.com</div>
<div>; (2 servers found)</div>

<div> </div>
<div>After a few hours the domain is again not resolvable as in point 2.</div>
<div> </div>
<div>Flushing the requestlist and domain groupinfra.com from cache fixes again this issue.</div>
<div> </div>
<div>I am using unbound 1.4.7 on OpenBSD 4.5.</div>
<div> </div>
<div>Compile options:</div>
<div>./configure --prefix=/opt/unbound-1.4.7 \</div>
<div>--with-ssl=/usr \</div>
<div>--with-libevent=/usr \</div>
<div>--without-pthreads \</div>
<div>--with-chroot-dir=/var/unbound \</div>
<div>--with-pidfile=/var/run/unbound.pid \</div>
<div>--with-conf-file=/var/unbound/etc/unbound.conf \</div>
<div>--with-username=named \</div>
<div>--disable-gost \</div>
<div> --with-ldns-builtin</div>
<div> </div>
<div>I'm <font face="Arial, sans-serif">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.</font></div>
