(RADIATOR) Radiusd stops with no warning

[Hugh Irvine]

Hello Kevin -

I will need to see a copy of your configuration files (no secrets) 
together with the corresponding trace 5 debugs showing what is 
happening. From what you describe below it sounds like there may be 
filters getting in the way somewhere.

regards

Hugh
