Session.invalidate() does not release sessions

           Summary: Session.invalidate() does not release sessions
           Product: Tomcat 4

          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Major
          Priority: Other

Hi

I have web application in which I have a logout page where I call 
session.invalidate().  This does not seem to work and session count just keeps 
rising as more users access the application and even if they logout the count 
does not go down.  The session count does go down after session timeout time is 
reached.  But still tomcat never releases memory though, it just keeps growing 
and ultimately crash with out of memory error.

I monitored this uing tomcats manager application's manager/list call

The problem here is 
1.  Tomcat does not release sessions that are invalidated.
2.  Tomcat does not release memory after the sessions that are released after 
session timeouts.
3.  Tomcat persists the sessions from previous run too.

Please help
