Does freeradius support considering a session as ended if enough accounting packets are missed?

I'm running FreeRADIUS Version 2.1.12. I've searched online, and haven't found anything on the subject that definitively says. Does freeradius support marking a session as ended/stopped if enough accounting packets are missed? One thing I did consider is that if not, I could try building a script that runs frequently, looking for sessions that have no accounting in the last X minutes, and changes the session to being ended (I think radzap is the tool for this, but I could be wrong). Of course, the less weird scripts I make (and have to come back and figure out what "clever" thing I did in 3 years), the better. -- Erik Andersen Eastern Oregon Net, Inc
