Stale Sessions

[Shane McKinley]

I have searched and searched, read the archives, etc. I feel that I may
have a unique problem and just missing a piece of the puzzle.
 
I have been running freeradius with a mysql database for over a year
now. It is very stable and I am generally pleased.
 
I have been having stale session issues on every one of my NASes. They
range from Cisco 7200, Cisco 2600, and Livingston Portmasters. They all
have stale sessions in the mysql database that never recieve a stop
time. I am almost certain there are no network issues because it seems
that start packets are never lost or update packets either.
 
This is the aaa config on my Ciscos:
 
aaa new-model
!
!
aaa authentication login default local group radius
aaa authentication login telnet line
aaa authentication ppp default if-needed local group radius
aaa authorization network default local group radius 
aaa authorization network iemcdslauth group radius local 
aaa accounting delay-start 
aaa accounting update newinfo
aaa accounting network default start-stop group radius
aaa session-id common
!
radius-server attribute nas-port format d
radius-server host X.X.X.X auth-port 1645 acct-port 1646
radius-server key 7 XXXXXXXXXXXXXXX
 
So the question is, why are my NASs not sending stop packets, or why is
the freeradius server not processing the stop packets?
 
Is this a common problem? Feel free to also point me to some documents
that may be of assistance. Maybe I don't have enough resources to
process the commands? I have about 1500 users.
 
This is my setup:
 
openSuSE 10.2
Freeradius 1.1.13
MySQL 5.0.26
128MB RAM
Pentium III
 
Thanks for any help,
 
Shane
