Hi all, I noticed that my radiusd process exited silently this morning without any notice before I must start it manually at Mon Dec 21 10:42:23 2009 as you can see in the below log messages. Besides, no crash is recorded in /var/log/messages. Any recommendation to troubleshoot this problem is appreciated. Sun Dec 20 21:37:51 2009 : Error: [sql] stop packet with zero session length.
