Well... the problem only persist sometime.. let say once or two
timeseveryday. The communication between Radius box and NAS using STP
cable.

Currently we are still on development stage of hotspot system. Before
implement them on big area, we found some problem, like explain above.
When I log in and log out or shut the notebook down without logout, I
can see both start and stop the record on radacct table,

I could not find the problem sources.. perhaps someone else has face the
same problem ?

Well.. with simultaneous-use:=1, the same user will not be able login
anymore because radius see that he / she still online.
