knotify4 is eating up the CPU

Problem

Sometimes the process knotify4 eats up the CPU cycles. I don’t know exactly what it is good for and why it is launched when I use Gnome, but it’s there. How to get rid of it?

Solution

When I see this process running, I always kill it (killall knotify4). As a more permanent solution, I made it unexecutable:

sudo chmod 644 /usr/bin/knotify4
sudo mv /usr/bin/knotify4 /usr/bin/knotify4.bak   # update, the previous step was not enough

I hope that’s the end of the story :)

Update (20111013)

Just a few minutes ago my CPU was under heavy load again. I checked “top“, and guess who was the guilty one again? Right, knotify4. I had already renamed it to knotify4.bak but something (maybe an update) restored the /usr/bin/knotify4 file :) Damn… Maybe we should write a crontab job that checks once a day if this f* is there.

I found some info about knotify4 here. Apparently, “knotify4 is required for delivering all notifications in KDE, including sound, text to speech, visual, command execution and taskbar flashing…” But why does it want to burn the CPU? No idea…
