<br>
Yes, that's exactly what I've done. It does try both masters,
eventually, but seems to get stuck on the "missing" one, and (from
the log messages) seems to back off from doing anything due to the
errors. I'd have expected it to query both masters in quick
succession on receipt of a NOTIFY, and treat an unresponsive
master independently of a responsive one.<br>
<br>
This is with the latest Centos 7 RPMs on the 4.1 branch. Also note
that I'm using TSIG and IXFR (I saw the same behaviour with AXFR).<br>

looking to deploy PowerDNS in a slave configuration that has
multiple (BIND) masters. In a test rig I'm finding that if I
have dual masters configured on a PDNS slave, and one of the two
masters is unavailable, the slave is querying the absent master
and not failing over to the other. <br>

And even if it receives and accepts a NOTIFY from the functional
master, it still sends the SOA query to the non-functional
master.</blockquote>
<p>The first question is: what version of PDNS Authoritative are
you using?</p>
<p>The second is just to confirm how you have configured each zone
with multiple masters in SQL: is it a single row with a
comma-separated list of masters?</p>
