I run 2 BIND 9.4.1-P1 servers doing 500-100 qps behind a firewall. The
queries do not stop when the firewall is rebooted. After a firewall reboot,
trying to resolve a query that failed usually results in a servfail. The only
way to get this query to resolve is to restart named. I've waited days to see
if some cache gets cleared and the queries will resolve as expected but this
The settings I've tried playing with are:
The problem can be reproduced by setting up a bind server, automating a lot of
queries at it, unplugging the network cable for a minute, reconnecting the
cable and retrying the queries that ran while the cable was unplugged.
Much appreciated if anyone can provide any insight.
