  2147483647 is 2^31-1.  It looks like a signed/unsigned problem to
me.

  Which is a weird number.

  Maybe.  See the SQL queries.  If the NAS is sending
Acct-Session-Time, that goes into the column.  If it doesn't send
Acct-Session-Time, then the session time is calculated based on the
local system time, and other info.

  It looks to me like the clocks on your NAS and the RADIUS server may
be quite a ways off from each other.
