           Summary: Long running threads created in servlet init never die
                    when webapp reloaded
           Product: Tomcat 5
           Version: 5.0.28
          Platform: All
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: pnidem@gmail.com


I create a long running (low priority) daemon thread in the init method of a
servlet and everytime the webapp is restarted the init method is called and a
new thread is created. As far as I know there is no way to kill threads that
have already been created. 

If a webapp were restarted continuously then eventually the server will run out
of memory because of all the running threads created in the init method.

To give you a little more context, the purpose of the long running thread is to
remove objects out of a cache if they have expired by waking up periodically and
looking for expired objects in the cache. There may be other solutions to this,
but it is still a problem that these threads get created and there is no way to
clean them up.

Servlets have a destroy method and there are ServletContext listeners which are
fired on webapp shutdown.
