I have the same problems with our validating unbound instance.
I suspect that this has to do with

failing with timeouts, while dig +dnssec +norec +vc dnskey uspto.gov
@dns1.uspto.gov.
dig +dnssec +norec +vc dnskey uspto.gov @dns2.uspto.gov.
work fine ... with a 1736-byte answer. Probably the fragmented
UDP response is getting lost somewhere near the authoritative
servers themselves.
But wouldn't it fall back to TCP then? Also with dig +cd I got an
instant answer, and the (old) cache dump contains the dnskey.
So I don't think that's the full story.
