Re: problem shuting down tomcat

hi all,

yes, I call the logout method for every session that I have createdand the problem remains...

eventually the tomcat shuts down itself after some timeout (or for anyother reason that I don't know) but only after at least 15 minutes.

with the jconsole I can see that after the shutdown script it's calledthere are still 17 or 19 threads running but only 15 or 17 are daemonthreads,

the other ones I don't know what they are.

I suspect that the problem is related with this 2 threads that onlyafter they desapear the tomcat will die.


does anyone knows something about this?


thank you all in advance.

cheers,

bruno coelho

I get that same issue when I try to download content from jackrabbitvia aservlet. No idea why, as the logout is in the "final" clause, and Icanassure you that the downloads actually work and close. I bring thisup,
because I don't get these straight away, only periodically (on garbage
collection I expect), and on tomcat shutdown. Do you do anythingsimilar?
ObjectContentManager s = null;
InputStream in = null;
try {
   s = getSession();
   Node node = s.getSession().getNodeByUUID(id);

   // Return a blank response
   resp.setStatus(200);
   resp.setContentType("application/octet-stream");
   in = node.getProperty(data).getStream();
   IOUtils.copy(in, out);
   in.close();
   in = null;

   out.close();
} catch (org.apache.jackrabbit.ocm.exception.RepositoryException e) {
       if (e.getCause() instanceof ItemNotFoundException) {
               resp.setStatus(404);
       } else {
               logger.error(e, e);
       }
} catch (RepositoryException e) {
   logger.error(e, e); //e.printStackTrace();
} catch (MalformedURLException e) {
   logger.error(e, e); //e.printStackTrace();
} catch (IOException e) {
   logger.error(e, e); //e.printStackTrace();
} finally {
       if (in != null)
               IOUtils.closeQuietly(in);
   s.logout();
}

hi all,
I'm having a problem shutting down the tomcat where the jackrabbitweb-app
is deployed.
I have scripted a set of tests to run before and after every changein the
code.

in the script I start tomcat with the startup.sh command.
then I wait until the tomcat finishs loading and then I run thetest using
junit.
after that I try to shutdown tomcat using the shutdown.sh script.
in the catalina.out log I can only see some unclosed session andnothing
else:
21.09.2009 15:16:26 *WARN * SessionImpl: Unclosed session detected.The
session was opened here:  (SessionImpl.java, line 1579)

running process tomcat is still there...

can you help me in the problem?
do you have any idea why this happens?


thank you all in advance.
