[gentoo-user] knotify4 is having a hissy fit again

Just woken up the box from sleep and within a minute I was alarmed by the fan 
racing up and the temperature showing 71.0-76.0C

Top showed that one of the two knotify processes was consuming 100% of CPU:

I thought of sharing what I saw above as this is not happening that often on 
my laptop.  I know that others have also reported knotify playing up.  

The only KDE application that I was running after I woke up the machine from 
sleep was kmail-1.13.7 (KDE-4.6.5)

Is there an update on this problem that you know of?

After some further investigation it is worth reporting that the problem was 
caused not by knotify, but by kdeinit!

I exited X and stopped xdm.  Only one knotify4 was left running as well as the 
kdeinit, both pegged at 100% and neither would go away after the X session had 
exited.  I was able to kill -15 the knotify PID, but the kdeinit would not 
shift until I used kill -9.

It's actually kded4 causing the problem, and it is a known issue.
killall -9 kded4 gets things working again.

You're right - was posting from memory, which is not what it used to be!  I am 
convinced that by the end of the day I am experiencing some badblocks.  ;-)
