FR suddenly doesn't respond any more and eats all cpu

[Benedikt Panzer]

Hello everyone,

I've configured here a FreeRADIUS 1.0.4 and I'm running it now to handle 
test requests. First, everything looked ok. FR responded all requests 
correctly. But suddenly it didn't respond any more to RADIUS requests 
and I saw it used 1 of my 2 cpus completly. Before it took between 1-2 
percent of the cpu. FreeRADIUS even could not be killed by a normal 
kill, I needed kill -9 to terminate it. It's very strange to me that 
happend after half an hour normal behavior. Then I started FreeRADIUS in 
debugging mode (-X) but then the error didn't occur until I stopped it 1 
day later. Just now I ran it again in not-debugging mode and again after 
about half an hour the same strange error: processor load about 99% and 
no responses to any requests. And at the moment there are really few 
RADIUS requests.

As I wrote, I don't have any debugging output before the error occured. 
The error doesn't occur when running in debugging mode. It doesn't want 
to be caught ;-)

Nevertheless, has anyone yet seen such a behavior or has an idea where 
to look or a guest for the reason?

Thanks a lot, Benedikt
