"me too", I get exactly what you are getting.  If you are always 
fiddling with FreeRADIUS I recommend you always run it in gdb as then 
you can get things fixed easily.

I usually build FreeRADIUS (under Debian stable) with:

It's when I add (I am pretty sure it's the in the first 8 or so 
patches) the following I get the same problem with FreeRADIUS:

I guess at this point I am going to be told to be a good boy and run off 
and use git bisect? :)

Looking through the patches normally I cannot see what could have caused 
the graceful exit...which is exactly what I am getting:

Happens about twice a day....completely unrelated to the load on the 
server.  Quick 'fix' is to back up to commit 
9261f3e0026323b2c397af13d02fbc5780908143.

Cheers
