It is called stale session. I am also trying to solve the same. I just
discussed this topic few days back. Check the list archive for
previous detail discussion on how to solve this.

every problem is unique (based on your business logic) . You need to
check the "racacct" table periodically to detect such problem (based
on your implementation) and come up with your own SQL to modify this
table (again based on your implementation).
