Do you have the startup log? (20130226.log)
That'll give you an idea as to what's failing to load and what needs to be fixed in order to get radius to start.
Here is the log of when I tried to start.

Make sure the hostname can resolve to the interface addresses. I've seen something similar before where the hostname resolution fails and adding an entry in /etc/hosts allow's SBR to start.
I have already done that and the hostname is resolvable.
Does it resolve localhost and the configured IP?
There was a typo on the hosts file, had the hostname wrong, fixed it and the service started
Thanks!
