Hello everyone, this is my first post so please forgive if I ask wrong question or post wrong forum. Best wishes all!
My question regards named/bind. I am running stock installation virtualmin (latest version) on top of webmin. IPv6 disabled on network interface and in named.conf
When I issue a “stop” command to the named service (“service named stop”, or use Virtualmin/webmin Apply Zone link), there is very long delay before command is complete. Start command is instant.
In /etc/init.d/named there is a line
NAMED_SHUTDOWN_TIMEOUT=${NAMED_SHUTDOWN_TIMEOUT:-20}
I changed to -2 but not decrease delay of service stopping.
Watching /var/log/messages, I see the “Shutting Down” message, but only after the long delay and many error (network unreachable) errors scroll, looks like most are attempts to resolve ipv6 addresses.
Thus every change in DNS options for any domain take much time while user waits for screen to load.
Advise suggestions welcomed!
Thank you!!!
Here are logs during shutdown. This set of entries appears after the long delay.
