Knotify & CPU Usage

Frequently I notice my CPU temps as shown by ksensors are sky high for no particular reason.

When checking system usage I find a program by the name of “knotify4” is using over 50% 0f the cpu. Killing the app seems to fix the high temp.

On checking the installed list of SW apps via the SW installer I am unable to locate such a program.

Any ideas?

knotify is part of another package. In the software installer in Search check the item ‘RPM provides’ when performing a search and it will tell you in which package it is. I think it’s in kdebase4 packages, which you cannot remove.
I see you’re still running the 4.1.3 version of KDE4. Upgrading to KDE4 4.2.4 would solve this matter AFAIK
