Radius stale sessions

[Renato Sousa]

Hello everyone,

I am fine-tuning the radius accountig sql information and noticed that
there are multiple stale sessions.
I would like to use a script in cron to delete these sessions but I have a
question.

How should I select a session as stale? Time difference (acctstarttime and
now()) ? Other records with the same mac-address and open sessions
(acctstoptime is null) ?

Regards,
