Re: [powerdns] port 53: Address already in use

The service restart apparently didn't stop the running instance. How did you restart it?

Anyway, you could try finding out what process is using the port, e.g.:

# netstat -putan | grep LISTEN

Get the process id that is listening on port 53, kill it and start the service.

Re: [powerdns] port 53: Address already in use

ok thanks i tried to kill the process but it don't works
powerdns relaunch the daemon
if i stop the service
/etc/rc.d/pdns stop
there is no program listening on port 53
and no error in var/log/error.log
and when i start the daemon
there is a program listening and the error
