Subject RE: Tomcat 4.1.30 not shutting down correctly
Date Wed, 27 Oct 2004 16:19:38 GMT

Hi,

It's a bit of a black art ;)  Or a $$$ profession, depending how you
look at it ;)  But in this case it's fairly simple:

- You've run shutdown.bat/shutdown.sh, so all the Tomcat threads should
be gone.
- The core JVM threads (main, EventNotifier, Finalizer, etc.) cannot be
gone until all other threads are finished, so these should be there.
- Whatever shows up in your thread dump (obtained from SIGQUIT) that's
not a core JVM thread is an offending thread.  From its class name or
the locking object, try to figure out what library or section of code is
responsible for this thread.
