MRob,
It is tremendously helpful if you let us know which version of PowerDNS
you
are running and on which platform.
We are aware of some versions of PowerDNS having this issue but we need
to
know what you are running.
I'm sorry I left that out. I installed using apt-get on Ubuntu. Package
is called:
pdns-server 4.0.0~alpha2-3build1
pdns_server --version reports "Authoritative Server 4.0.0-alpha2"
Since you have heard reports of this before, do you know if the problem
only happens on lightly used systems? In other words, if I move it to
production where queries happen on a regular basis, will the DB
connection not go stale?

I have a mysql-backed authority set up locally serving the internal

I
think more than 5 minutes, if not a lot longer), the queries will
start
working normally again (status NOERROR).
It appears I can cause the same problem prematurely by restarting the
mysql
service, which is what leads me to believe PDNS is not refreshing
stale
database connections right away (though eventually it does).
Restarting the authority of course fixes the problem, but I'm looking
for a
better solution.
Help?
