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. salmin@salmin:~$ sudo strace -p `pidof kded4` 2>&1 | head Process 19456 attached - interrupt to quit read(8, 0x6d5cb4, 4096) = -1 EAGAIN (Resource temporarily unavailable) poll([{fd=3, events=POLLIN}, {fd=8, events=POLLIN}, {fd=5, events=POLLIN}, {fd=9, events=POLLIN}, {fd=11, events=POLLIN}], 5, 0) = 0 (Timeout) read(8, 0x6d5cb4, 4096) = -1 EAGAIN (Resource temporarily unavailable) read(8, 0x6d5cb4, 4096) = -1 EAGAIN (Resource temporarily unavailable) poll([{fd=3, events=POLLIN}, {fd=8, events=POLLIN}, {fd=5, events=POLLIN}, {fd=9, events=POLLIN}, {fd=11, events=POLLIN}], 5, 0) = 0 (Timeout) read(8, 0x6d5cb4, 4096) = -1 EAGAIN (Resource temporarily unavailable) read(8, 0x6d5cb4, 4096) = -1 EAGAIN (Resource temporarily unavailable) poll([{fd=3, events=POLLIN}, {fd=8, events=POLLIN}, {fd=5, events=POLLIN}, {fd=9, events=POLLIN}, {fd=11, events=POLLIN}], 5, 0) = 0 (Timeout) read(8, 0x6d5cb4, 4096) = -1 EAGAIN (Resource temporarily unavailable) 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
