Description Cosmin 2009-05-20 21:27:34 UTC 
Version:            (using KDE 4.2.3)
OS:                Linux
Installed from:    SuSE RPMs

I think it happen after update of kde or qt (i did "update if newer version available" on two opensuse systems). Kded4 remains at 50% cpu load.

What does top say? This is most likely from the X server or graphics card drivers or something. Otherwise, we need some actual profiling information. 

There are general speed-ups between your version and 4.3beta.

Hello! I've just installed kde 4.2.3 from debian-desktop.org.

The kded4 process is loading cpu to 100%.

If it's important I can add some information about fd
salmin:/proc/19456/fd# ls -l 8
lrwx------ 1 salmin salmin 64 Май 22 22:00 8 -> socket:[15602558]
salmin:/proc/19456/fd# netstat -p | grep 15602558
unix  3      [ ]         STREAM     CONNECTED     15602558 19456/kded4
