Repeated Deploys of WAR Generate OOM Exception

Hello,

I have just run a test that tests Geronimo's ability to redeploy .war
files. The results don't look so good, but I'm hoping the info I've
collected will help expose the problem (whether the problem is with me
or the server

I've included the script, .war file, web.xml, and two exception traces
(one from the deploy client and one from the server) I apologize for
the length of this post. If there's a better way to include all this
information, please let me know.

It appears as if the server is running out of memory. Note that I did
not alter the native configuration of Geronimo in any way. This is a
stock M3 download, using JDK 1.4.2_05 on Windows XP SP2.

It's my expectation that the app server would stay up and running
indefinitely after redeploys of .war files. Especially this .war file
since it merely contains a single welcome.jsp. I hope this info is
helpful, and let me know what else you might need. I'll gladly send
the script and .war file to others that might want to test this.

Thanks,
Seth

My test script:
$ cat over-and-over.sh
while /bin/true; do
java -jar bin/deployer.jar --user system --password manager deploy ../eclipse/wo
rkspace/MinimalWebapp/build/minimaltest.war
sleep 1
wget -q -O - http://localhost:8080/minimaltest/welcome.jsp > /dev/null
java -jar bin/deployer.jar --user system --password manager undeploy minimaltest
sleep 1
done

Structure of minimaltest.war:
$ jar tf ../eclipse/workspace/MinimalWebapp/build/minimaltest.war
META-INF/
META-INF/MANIFEST.MF
WEB-INF/
welcome.jsp
WEB-INF/web.xml

Contents of web.xml:
$ cat ../eclipse/workspace/MinimalWebapp/web/WEB-INF/web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/
xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
<welcome-file-list>
<welcome-file>welcome.jsp</welcome-file>
</welcome-file-list>
</web-app>

So, as you can see, it's a very minimal webapp. It doesn't initialize
anything, nor does it include any 3rd party jars or libs. It doesn't
even load up any classes, and the welcome.jsp only says "Hello,
world!"

After 1434 deploy cycles, we receive this exception from the deploy client:
