Hi to all! We have an issue with a FreeRADIUS server (FreeRADIUS server and Oracle Database). Sometimes it fails and stops to process the AAA requests (only complete server reboot helps)! Here is the log output during the time of a failed situation: [root@aaa0 ~]# tailf /usr/local/var/log/radius/radius.log Mon Dec 13 19:25:12 2010 : Error: rlm_sql_oracle: Oracle logon failed: 'rlm_sql_oracle: no connection to db' Mon Dec 13 19:25:12 2010 : Error: rlm_sql (sqlacct) in sql_accounting: stop packet with zero session length.

Mon Dec 13 20:09:51 2010 : Error: There appears to be another RADIUS server running on the authentication port 1812 [root@aaa0 ~]# reboot Please, advise what can be the reason of such negative behaviour of the RADIUS server? Why does it lose connection to a db? How can we troubleshoot the issue further? Alexander
