[Pdns-users] Authority not refreshing stale mysql connections?

I have a mysql-backed authority set up locally serving the internal LAN
domain on a test platform (very lightly used at the moment). It appears
that after some time (hours), the DB connection goes stale and queries
return with dig reporting status SERVFAIL. If I wait (not sure how long,
but 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.
