Thanks Alan.
I tried to start and stop the service but it is the same.
When I restart the service, I get the socket error, if I delete the
socket
file and check debug, I get the bind error. And this keeps repeating
until
I reboot.
What OS are you using?
On Debian / Ubuntu for example if it's started as systemd unit, you can
find it this way:
$ systemctl list-units | grep radius
and then stop it with
$ systemctl stop <radius unit name from above>
