[Unbound-users] Unbound stop working without error-log

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?

Thanks

Andreas
