Dear  Alessandro,

    Thank you very much for your help.

    I had adjusted Qt4.8.3 as you suggest, but the issue is not resolved...

    The problem I encountered makes me confused.
    My application is a simply QtWebkit based browser and it running on
MIPS embedded linux platform without SWAP.
    But when I visited  http://www.youtube.com/leanback#search?q=a and looked
over the contents of searching result one by one, the system memory usage
kept  increasing.

    I think it could be Qt related problem because I has disabled all the
cache in Webkit by QWebSettings's API.

    For more information :

Regards,
FF
