<div dir="ltr"><pre>I think I am hitting the same problem reported back in 2012:
<a href="http://www.unbound.net/pipermail/unbound-users/2012-July/002467.html">http://www.unbound.net/pipermail/unbound-users/2012-July/002467.html</a> with
Unbound 1.4.22.
I thought it was a problem with the package from my Linux distribution, but
it actually was reproducable from the source code too. I started from an
fresh EC2 instance and did the steps below. I created two configurations:
one forwarding to 3 addresses, 2 of which were unresponsive (the
10.x.x.x.), and another stubbing to the same addresses. With the forward,
all lookup happened quickly and none failed. With the stub, the first few
timed out (30 sec). When I repeated the lookups, the first few timed out
again.
I included Unbound's log for the stub case in <a href="http://pastebin.com/Ww9ykJX2">http://pastebin.com/Ww9ykJX2</a>.<br>What I noticed is that the unresponsive addresses were attempted multiple <br>times consecutively. In the case of the forward, they were skipped immediately.
Is there a fix for this?
Thanks.
