[Unbound-users] Problem with query

Paul,

Are you SURE your server returns?  I just tried it with:

dig +time=600 +tcp @193.110.157.136 -t ns dir.slb.com.

And it doesn't return AT ALL.  (That is a 10 minute wait time!!)

No logging is on.   But, if you turn it on, you'll see unbound working
"forever".

I don't have any "harden" stuff on.    I do have:

val-permissive-mode: yes
module: iterator

My "guess" is that by the time Unbound resolves all the NS records to
A records, some have expired and it goes back and does the resolution
again.  Thus an infinite loop?
