I have Fedora 15 on both my desktop and notebook. In both, I noticed the
increasing
memory load. That happens even if I'm doing searches only, but when I started
to perform
replace operations as well, the system seemed to demand a memory increase even
faster.
Perhaps if someone who's also using Fedora could test and report if the same
happens to
him (her).
If you can suggest any other test I could perform on my box, please let me know.

The installed qt are version 4.7.4-2:
qt-4.7.4-2.fc15.x86_64
qt-webkit-4.7.4-2.fc15.x86_64
qt-x11-4.7.4-2.fc15.x86_64

They're the most updated versions provided by F15.
