I'm getting the same problem with JBoss 3.2.1_Tomcat-4.1.24.
In my case, it seems to be triggered by a strange
interaction with the Struts libraries. I threw together a
quick script which continuously re-deploys the
struts-example.war file over and over again (with a 15
second pause between deploy/undeployments) by popping the
file in and out of the deploy directory (instead of using
the deployer.jar tool...not sure at this point if that would
make a difference)
Sure enough, when watching the GC output, the memory use
keeps increasing. If I stop the script, the memory doesn't
seem to ever get reclaimed.
If I leave it running, eventually the server blows it's heap
and I start getting OutOfMemory errors at random intervals.

After leaving it for about an hour in this state, with GC
details turned on, we can see that sure enough, the memory
is not being reclaimed, despite the JVM's best efforts...

> Key: JBAS-88
> URL: http://jira.jboss.com/jira/browse/JBAS-88
> Project: JBoss Application Server
> Type: Bug
> Versions: JBossAS-3.2.6 Final
> Reporter: SourceForge User
> Assignee: Scott M Stark
>
>
> SourceForge Submitter: nobody .
> This behavior has been observed on Windows 2000 SP2,
> running Sun JDK 1.3.1 and jBoss2.2.2 both Tomcat and
> Jetty bundles.
> After many EAR hot redeployments in a short period of
> time, (prehaps one every 5 to 20 minutes over a period
> of 6 hours) a redeployment will result in "Out of
> Memory" exceptions being thrown.
> This happens with both the Tomcat and Jetty bundles,
> but the error is much more clear with Jetty. In the
> case of Tomcat, it appears to redeploy correctly but
> creates a variety of errors when the app is run.
