[Unbound-users] SERVFAIL then proper reply

Hi Stephane,

I think this is a result of a bug I already fixed, which barfed the
security status after taking a query from the cache a second time.

In your logs this seems to happen for, which
loses the secure status for its DLV answer, which in turn makes the
DLV lookup error, which generates the servfail.  Why the second lookup
then succeeds I do not understand.

I hope the bug is fixed in 1.3.1 (just with release candidate), 
otherwise I'd like to look at a higher verbosity log for it.

Best regards and thanks for reporting,
