This reminds me of the issues we have when using Unbound with DNSSEC  
validation *and* using a forwarder. For some time it was Unbound using  
Bind 9.7.4 as parent but it also happend with a second Unbound  
instance as parent that Unbound stop resolving any names, because of  
some obscure validation failure. We have "solved" the problem by  
setting the internal Unbound to not validate and let the forwarder do  
the DNSSEC work.
