I can see no pattern in my radius.log that is consistent for all of the 
exits.  As this server is fairly quiet /var/log/messages is really quite 
empty:

an example

Dec  4 12:54:26 cata su: test to root on /dev/pts/1
Dec  5 05:14:57 cata kernel: pid 68292 (radiusd), uid 133: exited on 
signal 11
Dec  5 08:39:50 cata su: test to root on /dev/pts/1
Dec  5 08:51:23 cata slapd[93791]: OTP unavailable because can't 
read/write key database /etc/opiekeys: Permission denied
Dec  5 20:47:11 cata kernel: pid 79883 (radiusd), uid 133: exited on 
signal 11

top is also similarly boring.....at the present, I don't know what it 
looks like just after FreeRADIUS exits.  I will investigate it next time 
it happens.

Regards,

Hugh
