Fail to restart radiusd

[Yang Xue]

Hi,

We're running freeradius server v2.0.3 and restart of the daemon failed with:

#/etc/init.d/radiusd restart
Stopping RADIUS server: [FAILED]
Starting RADIUS server: Fri Jul 16 07:50:16 2010 : Info: Starting -
reading configuration files ... [FAILED]

In the radius.log, it shows:

Error: There appears to be another RADIUS server running on the
authentication port 1812 <---

The odd thing is that there is no radiusd process running on the Linux
server at all:

# ps aux  | grep rad

Does anybody know why it complains about "another RADIUS server
running on the authentication port 1812" although there is no existing
radiusd process at all?

Thanks.
