Failed to open socket

[Lemaster, Rob]

I recently upgraded to 2.0.4, and now I'm seeing the following error when I start FreeRADIUS:
 
radiusd -X:
/opt/freeradius-2.0.4/etc/raddb/radiusd.conf[210]: Error binding to port for 0.0.0.0 port 1812
 
radius.log:
Sat May  3 20:21:39 2008 : Error: ERROR: Failed to open socket: 
Sat May  3 20:21:39 2008 : Error: /opt/freeradius-2.0.4/etc/raddb/radiusd.conf[210]: Error binding to port for 0.0.0.0 port 1812
Sun May  4 01:37:24 2008 : Info: Ready to process requests.
 
I tried hardcoding the IP & Port in radiusd.conf, but it didn't make any difference. I reviewed posts to this list and found others have seen similar errors, but their fixes didn't apply to my situation. 
 
Any suggestinons?
Thanks!
