Warning "stop packet with zero session length" and the difference between number of Radius requests and responses

[Dinh Pham Cong]

Hi all,

I set up a FreeRadius server to receive accounting start/stop packet from
GGSN. Then FreeRadius will save the information into MySQL database.
However, I see that there is a different between the number of received
packets and the Radius response to GGSN

[root at radiusd2 sbin]# ./radmin -e "stats client acct"
        requests        422959
        responses       412155
        dup             0
        invalid         0
        malformed       0
        bad_signature   0
        dropped         0
        unknown_types   0

I understand that if GGSN sends an accounting start packet to Radius, it
should make a corespondent response or GGSN will resend the packet. So I
don't know why there is such a difference. Meanwhile, radius.log is filled
with a lot of messages like those:

Any suggestion would be appreciated.
