JSF: partial page rendering is causing memory leak leading to outofmemory

Question

JDeveloper 10.1.3.2.0
JDK: 1.6.0_06
Operating System: Windows XP.
I test my application for memory leaks. For that purpose, I use jconsole to monitor java heap space. I have an edit page that has two dependent list components. One displays all countries and the other displays cities of the selected country.
I noticed java heap space keeps growing as I change country from country list.
I run garbage collection and memory usage does not go down. If I keep changing the province for 5 minutes, then I hit a java heap space outofmemory exception.
To narrow down the problem, I removed the second city component and the problem still exists.
To narrow it down further, I removed autosubmit attribute from the country component and then memory usage stopped increasing as I change country.
country/city partial page rendering is just an example. I am able to reproduce the same problem on every page where i use partial page rendering. My conclusion is PPR is causing memory leak or at least the autosubmit attribute.
This is really bad. Anyone out there experienced same issue. Any help/advice is highly appreciated !!
Thanks

Samsam,
I haven't seen this problem myself, no.
To clarify - are you seeing this behaviour when running your app in JDeveloper, or when running in an application server? If in JDeveloper, a copuple of suggestions:
* (may not matter, but...) It's not supported to run JDev 10g with JDK 6
* have you tried the [url http://www.oracle.com/technology/pub/articles/masterj2ee/j2ee_wk11.html]memory profiler
Best,
