we have a FR server (version 1.1.7) on a Redhat machine. We use it for dumping accouting requests into a database. We have about 200 requests per second in average.
Once in a while (1 per minute) we see a error in the log file: Discarding duplicate request from client ... due to unfinished request ....
The client hasn't received a response to the request, and is re-sending it. i.e. the request has taken LONGER than the client's timeout, usually 5 seconds or so. That indicates a pretty significant backlog of requests at 200 packets/s. It likely means that your system us barely keeping up with the load.
Does the FR server drop accouting requests?
No. But accounting requests should *not* be re-transmitted by the NAS. If the NAS does this, it often means that they don't quite follow the RADIUS standards.
How can we monitor how any requests the RADIUS server gets? Is this anything to worry?
You probably want to double-check your database. Tune it, optimize it, upgrade the hardware, whatever. Alan DeKok.
