And a good request for help includes the following information (and send it to 
webkit-help):

- What you are using. QWebPage doesn't really tell much. Which version 
of 
WebKit, which version of Qt do you use?

- What you are doing. E.g. do you use QtLauncher -r load.these.urls 
with 800 
entries for cnn. Or do you have custom code? If you have custom code you 
should post it to make sure you don't have a memleak in your code.


kind regards

It would be a great sign of respect if you read http://webkit.org/contact.html 
and start using webkit-help for these kind of questions.

Something that could be helpful is running your test batch w/
GtkLauncher too to see if the problem is qt-specific (i bet not) or at
least to check if it is even worse in qt port than others

Of course not.  File a bug on  with more detail than 
you've provided in your email messages (which Qt port you're compiling, e.g., 
where you got the source code, the revision/commitish of the source, which 
processor and operating system, which compiler, etc.).

Also, please move this discussion to .  The 
webkit-dev mailing list is to discuss future development of the WebKit engine.  
Thanks!

After I load "www.cnn.com" for 800 times consecutively, the virtual memory
size of my little program has reached 1600M; while the resident memory is
1500M
This is horribleIs this kind of memory leak expected?

[webkit-dev] Memory leak or should I clear content of QWebPage?

[Zongheng Zhou]

Hi, all
I just built a program in QT webkit, and noticed that the memory usage of my
program grows 1 or 2 megabytes as I load each web page.

My program is quite simple. I defined a global variable:
QWebPage mypage;

Each time when a new URL request comes, I call the following to load the web
page:
mypage.mainFrame()->load(url);

Anybody knows whether this memory jump Is because of memory leak in webkit?
Or should I need to clear the content in "mypage" after each loading (I
don't find any API to do this)?

Thanks in advance.
