freeradius 2GB problem

[Rahul Nakra]

I am using freeradius 2.0. With the default schema which comes with that.
Following is the database entry. It shows a new user never logged in before.
If i give value of Max-All-Data 2147483646 it works fine. Anything above it
doesnt work. Attached is the radius log where it displays negative value for
sqlcounter.

mysql> select * from radcheck;
+----+----------+--------------+----+------------+
| id | username | attribute    | op | value      |
+----+----------+--------------+----+------------+
|  1 | rahul    | password     | == | rahul      |
|  2 | rahul    | Max-All-Data | := | 2147483648 |
+----+----------+--------------+----+------------+
2 rows in set (0.00 sec)
