[jira] Created: (HIVEMIND-8) "OutOfMemoryException" after multiple application reloads

Message:

  A new issue has been created in JIRA.

---------------------------------------------------------------------
View the issue:
  http://issues.apache.org/jira/browse/HIVEMIND-8

Here is an overview of the issue:
---------------------------------------------------------------------
        Key: HIVEMIND-8
    Summary: "OutOfMemoryException" after multiple application reloads
       Type: Bug

     Status: Unassigned
   Priority: Major

    Project: HiveMind
 Components: 
             framework
   Versions:
             1.0

   Assignee: 
   Reporter: Jamis Buck

    Created: Mon, 21 Jun 2004 1:36 PM
    Updated: Mon, 21 Jun 2004 1:36 PM
Environment: Tomcat 4.x and 5.x. JDK 1.4.1. Gentoo Linux, 2.6.5 kernel. Hivemind 1.0-beta-1.

Description:
I have a Tapestry application that uses the HiveMindFilter servlet filter to initialize and teardown the registry. After reloading the application a few times, I get an "OutOfMemoryException" from Tomcat, and only a hard restart of Tomcat can fix it.

A coworker tracked the problem down and gave me a patch (for org.apache.hivemind.util.EventListenerList, in copyOnWrite(int)), which I will attach to this issue if I can (I'm not too familiar with this issue tracker).

[jira] Commented: (HIVEMIND-8) "OutOfMemoryException" after multiple application reloads

The following comment has been added to this issue:

     Author: Jamis Buck

       Body:
Sorry, didn't see that you had already responded when I posted the patch. Also didn't realize this patch had already been submitted.

I have absolutely verified the version I am running, and it is hivemind-1.0-beta-1. However, there is a chance that the error is occuring due to something else. I'll see what I can find.

Sorry for the noise.

[jira] Commented: (HIVEMIND-8) "OutOfMemoryException" after multiple application reloads

The following comment has been added to this issue:

     Author: Howard M. Lewis Ship
    Created: Mon, 21 Jun 2004 2:54 PM
       Body:
Just to be safe, I increased the size of the loop that adds listeners:

    public void testOutOfMemoryError()
    {
        Trigger ta = buildTriggers(1)[0];
        EventListenerList l = new EventListenerList();
        List iterators = new ArrayList();

        try
        {
            for (int i = 0; i < 500000; i++)
            {
                l.addListener(ta);

                iterators.add(l.getListeners());

                l.removeListener(ta);

            }

        }
        catch (OutOfMemoryError e)
        {
            fail("Ran out of memory!");
        }
        catch (Throwable e)
        {
            fail(e.getMessage());
        }
    }

That's a lot of listeners and it works.  If there was still an out-of-control doubling of size of the list (as in the original code) we'd run out of memory very quickly.
