only work with 5 users or clients

[Tom Miller]

I have a 7204 (12.0(22)S1) terminating DSL L2TP VPDN and 
freeradius ( 1.0.4)

I am having problem when number of users (clients) 
increase from 6 and up.

It worked fine when I have only 5 users (clients) using
the system.


I found the max_requests was set at 1024 in radiusd.conf and 
have inscrease the number up to 50 clients (50x256=12800)

max_requests = 12800



However,  It doesn't seem to have any effect. What am I doing
wrong.


One things I noticed.  The two users that can not connect 
will sent incomplete information
to the radius server from NAS (7204) such as:
