Because it has received the accounting request for the beginning of the
user's session (start request), but never received a corresponding
stop request. To check this, examine `radwho' output or simply
run `radgrep username'.

In short, this means one of the following:

1) the user is actually on line now,
2) the NAS is not sending stop requests (accounting requests with
Acct-Status-Type set to Stop).
3) stop request it sends is malformed and does not match
the start request.

Check points 2,3 above. In both cases you'll probably need to do some
configuration on your NAS side. Examining contents of the file
/var/log/radacct/<NASNAME>/detail will help you clarify the
situation.
