While using QtTestBrowser on N97 "Memory full" message is displayed on the Screen.
Steps to reproduce:
1.- On N97 Install Qt 4.6.2, QtWebkit.sis (QtWebkit 2.0)and QtTestBrowser.
2.- Launch QtTestBrowser and start loading pages
Actual Results:
Memory full message is displayed on the screen.
Expected results:
Browser would load several pages without any "memory full" warning.
Note:
This issue was not observed on previous QtWebkit builds. It was observed after week 20 build.

The N97 has apparently very little RAM available. I guess this issue is caused by the currently very high memory usage of QtWebKit.

Simon,
It will be also useful to check if QtWebkit.dll is being produced using BYTEPAIR compression (it should be to save lots of RAM). See http://bugreports.qt.nokia.com/browse/QTBUG-8203.
To check binary header (including compression type), use
elf2e32 --dump=h --e32input=\epoc32\release\armv5\urel\QtWebkit.dll

Increasing the priority from P3 to P2.
Alexandra, can you publish the actual pages you are loading - since these are live sites we can not really reproduce the exact same scenario, but if the issue is persistent, we should be able to reproduce the out-of-memory situation.
Sriram
i think we need to look at Siddharth's proposal. Similar issue was reported in Qt 4.6.3.

I have checked the http://pepper.troll.no/qtwebkit/weekly-builds/2.0/week22/qtwebkit-2.0-symbian.zip build and it is using BYTEPAIR.
