Hi Winfried,<br>
<br>
thank you for your reply.<br>
If it's a feature and can't be changed, I have a big problem that
I'll have to solve by changing the software to another.<br>
For example, Bind asks more than once if answer does not come. Users
are angry that DNS resolving does not work for them (of course, it
is to blame for authoritative servers of a specific domain). <br>
But I have to solve it somehow.<br>
<br>
Thanks.<br>
Mira<br>

Hi Mira,<br>
<br>
Yes the Recursor does no retry on *this* auth. But it tries on the
other nameservers from the NS RR set. IPv4 and IPv6. So if you
have only one auth, Recursor tries two times, IPv4 and IPv6 if
available.<br>

<pre class="k9mail">Hi,
I have a problem that I can't force the pdns recursor to query the
authoritative servers repeatedly if they do not answer. Recursor tries
the query only once and then return an error (SERVFAIL) to the client.
This is very problematic when the authoritative server is overloaded or
there are some problems on the network. I didn't find any way in the
configuration to change it.
Server version: 4.2.2-1 (from EPEL repo on CentOS 8)
Can anyone help?
Thanks.
