So it seems there is a dependency issue here after the last OS upgrade, but the problem is we preferred iptables over firewall and masked it long time ago on this system.

Troubleshooting this further and just letting everybody know. This problem occurred on another of our servers and I am afraid I have to re-open this issue. Restarting both bind and webmin doesn't help - both are running fine, but webmin doesn't see bind. When going to Webmin >Servers >BIND DNS Server it shows: BIND DNS Server BIND version 9.9.4, under chroot /var/named/chroot Start BIND Search Docs.
