I don't think Signal 10 is supposed to be handled by freeradius in some
way -- it just crashes. Producing a core dump proved surprisingly tricky
for me. 

Citing Alan's posting from Oct 11:

There's one more point at least: The core dump will always be created in
the Current working Directory of the respective process. On Linux, look at
/proc/<pid>/cwd. To my surprise, it turned out to be / (root dir).
(Hey, is this a bug or a feature?)
So somehow freeradius must be able to write to a core file there. 
I succeeded by pre-creating a file named /core and chown'ing it 
to the freerad user, but not before getting the ulimit business straight.

Good Luck
Martin
