****************************************************************
4.0 connection manager passed wrong parameters to PMI.
As a result, the number of connections released could be
greater than the number of connections allocated - that
derives the negative percentUsed.
Problem conclusion
Instead of using the numbers passed by connection manager,
PMI tracks related numbers itself. This fixes the problem.
