thread count keeps rising not released

[sameer sood]

Hi
I am working with hibernate 3.2 and mysql 5
The problem is that when i end sessions in hibernate the thread related to it are not released, the task manager in windows shows a rising thread count and as my server has max of 154 threads limit (which is a MYSQl bug).
The limit can be changed but my question is that when i do session.close(0
why are not the threads released.

this is my cfg

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
