Shutdown command does not terminate tomcat process

I use tomcat6 on Linux. I run tomcat with shutdown port
configured as follows:
  <Server port="8005" shutdown="SHUTDOWN">
    //...

After I start tomcat, I find that:

    # jps -l
    24819 org.apache.catalina.startup.Bootstrap
    25103 sun.tools.jps.Jps
    # 

Now when I issue SHUTDOWN command to tcp/8005, logs show that the
connectors are being shutdown:

   May 29, 2010 3:11:55 PM org.apache.coyote.http11.Http11Protocol pause
   INFO: Pausing Coyote HTTP/1.1 on http-8080
   May 29, 2010 3:11:55 PM org.apache.coyote.http11.Http11Protocol pause
   INFO: Pausing Coyote HTTP/1.1 on http-8443
   May 29, 2010 3:11:56 PM org.apache.catalina.core.StandardService stop
   INFO: Stopping service Catalina
   May 29, 2010 3:11:57 PM org.apache.coyote.http11.Http11Protocol destroy
   INFO: Stopping Coyote HTTP/1.1 on http-8080
   May 29, 2010 3:11:57 PM org.apache.coyote.http11.Http11Protocol destroy
   INFO: Stopping Coyote HTTP/1.1 on http-8443

But I find that the process is till running:

    # jps -l
    24819 org.apache.catalina.startup.Bootstrap
    25103 sun.tools.jps.Jps
    # 

why does this happen? Does not shutdown command to shutdown port
kill tomcat?

pl help,

/U

You most likely have a webapp that has started a thread on its own, and has failed to clean up properly when the webapp is stopped.  If you take a thread dump, you should be able to see the rogue thread.  Normally, one uses a ServletContextListener to stop your asynchronous threads during webapp or container termination.

Note that there's a FAQ entry for this situation:
