Hello we have unound 1.4.6 operating as caching resolver asking a border Bind 9.7 as forwarder. This has worked for some time but today we got trouble to resolve more and more domains/hosts. A restart a unbound cleared the problem for some time but it failed again after some minutes. There is nothing in the normal log either for the border Bind 9.7 or for unbound. I have captured one failing event (www.computeruniverse.net) on the wire an with unbound loglevel 4. The border Bind does resolve fine and quick, but unbound does not deliver the result further on. This has happened for many different domains over night according to mailserver logs. Any hints how to debug this problem?
