Dec \ 20 19:08:54 server pdns_recursor: Failed to update . \ records,
I see it trying to connect to root dns (watch -n 1 \ "lsof -i -n -P|grep

If there is a problem withconnection establishment and tracking, you could conceivableexhaust a firewall resource which would have the same symptoms:the updates work for a period of time and then stop http://juicecoms.com/failed-to/failed-to-replace-dns-a-records-for-owner-cluster.html
But it doesn't use root dns so it's not a fix. > > forward-zones=mydomain.org=127.1.2.3,.=172.16.1.1 > > To set ".=IP" works for all public dns > > > > Any help welcome records, RCODE=2 Aug 9 02:10:25 dilbert pdns_recursor: Failed to update .
