  What does that mean?  Is your NAS behind a flaky internet connection?

  If the user goes away, the NAS is supposed to sent an accounting packet which says "session is stopped".  If the NAS doesn't do that, then throw it in the garbage, and buy one that works.

  Which means that the session is still active.

  See 'cron'.
