RADIUS will no longer start!

[Michelle Gates]

All,

Our RADIUS server has been up and running fine for 127 days now. Suddenly
today it no longer runs. I tried to put it into debug mode and got the
following output:

Can anyone shed any light on this? Unfortunately for me, one of our
developers was working on our production server but *claims* not to have
changed anything of any consequence...

I'm really unsure of where this is coming from! Has anyone seen this error
before or could anyone at least point me in the right direction?

Best regards,
