The Acct-Session-Id is generated by the NAS that is reporting the incoming
connection. It only has relevance to the existing sessions on that particular
NAS. If you have multiple NAS's and/or if those NAS's are restarted or if their
couters roll over, you will have duplicate Acct-Session-Id's. This is normal
behaviour.

Radiator will always honour the existence of Proxy-State in a packet and will
preserve it across incoming and outgoing packets. Radiator itself however does
not use Proxy-State internally. Again, Proxy-State is used by some Radius
servers to maintain some state information about requests they are forwarding
to other Radius servers. I don't think there is anything to be interpreted
therein.
