After BIND update on Debian Lenny, Virtualmin can not detect whether it's running

Forget it, I found the solution on the bug tracker. See the issues tracker for a solution.

the solution is
go to Webmin -> Servers -> BIND DNS Server -> Module Config -> System configuration, and change the “Default PID file location(s)” to /var/run/bind/run/named/
ad it will be included into 3.79
