Description Yun Feng CLA 2010-12-29 20:09:10 EST 
Build Identifier: 3.6

The Browser widget created with SWT.MOZILLA has big memory leak issue in below scenario: reload the page every 5 secondes and keep moving the mouse over the page.
The memory goes from 90MB to 300MB in about 7 minutes, then the RCP application crashes.

The Java heap size of the RCP application is very stable, so the leak must happen in Native code.

Reproducible: Always

Steps to Reproduce:
A test application is attached, reproduce this issue with below steps:
1) Import XULRunnerTest.zip into Eclipse
2) Run xulrunnertest.Snippet267 with VM argument: -Dorg.eclipse.swt.browser.XULRunnerPath="your_xulrunner_path", I'm using XULRunner 1.9.2
3) The Yahoo home page will be refreshed every 5 seconds automatically.
4) Open Task Manager in XP to mornitor the memory usage of the RCP application.
5) Keeping moving the mouse over the Yahoo page. 
6) You will see the memory keeps growing quickly

The memory usage for this RCP is very stable if no mouse moving over the Yahoo home page.

Is anyone working on this defect?  Rational Business Developer has a customer APAR on this problem, and the customer is getting impatient for a fix.

Hi Grant. Thanks for the fix. Can it be backported to the 3.6x stream. Rational Application Developer needs a fix in that stream.
Comment 9 Ian Tewksbury CLA 2011-03-14 09:27:16 EDT 
Lakshmi,

I know Grant is out for the next few days.  Any chance you could look into bringing this back to 3.6.x stream for the adopter product that needs it?
Comment 10 Lisa Lasher CLA 2011-03-14 11:11:29 EDT 
Rational Business Developer also requires a 3.6.x fix
Comment 11 Silenio Quarti CLA 2011-03-14 11:50:17 EDT 
Please open a bug in the IES bugzilla requesting the back port (https://bugs.ottawa.ibm.com/).

Hi,

I don't have access to that system. Could you open it on our behalf?
