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. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
