CPU 100% all times

eliassal · 04-05-2015, 09:09 AM

Since a several days, I started to notice that my Fedora 20 is very slow, I ma using KDE and not Gnome. Wgen I fire system nonitor, I see RAM is around 60%, CPU shooting constantly 100 to 99%.

I opened a command line, ran top, getting "system-config-s" constantly not less than 95%

Thanks for your help

You need to get the full name of the process, "system-config-s" is truncated. Get the PID and then run "ps -fp PID" to get the full name. For example, in your output above, the PID is 64461, so you would run "ps -fp 64461".

Did you have any programs open when you ran "top"?

Also use [code] tags, not [quote] tags in order to maintain formatting when posting output here.

Thanks, here is the output

root 64461 1 90 Apr04 ? 22:26:57 /usr/bin/python /usr/share/system-config-services/system-config-services-mechanism.py

Yes, there were other programs running at the same time (Firefox, gedit)

I don't use Fedora at all, but system-config-services is, like the name indicates, a graphical service configuration tool. Do you see a window for it on your desktop? Do you remember running a service configuration tool (e.g. to enable to daemon to start at boot time) recently? If not, I usually figure it's some sort of buggy process that keeps running. My usual first course of action is to try to kill it (and then use "kill -9" if that doesn't work). If it goes away and doesn't come back, it's usually just a buggy program that got out of control...

Hi. When the daemons get out of control you have to kill them.

Code:

killall system-config-services-mechanism.py

But they may respawn. You have to erase them altogether to get rid of them.

Code:

 yum erase system-config-services

Daemons which cannot be controlled by their parents become zombies. The only way to get rid of them is to kill them or erase them. Haven't you ever seen the Walking Dead?

Yes I have run KDE services configuration, when I saw this, I rebooted, but still see this process in spite of the fact that I did not run any config applet

Is it still consuming 100 of the CPU? It might be something that's supposed to run in the background...

After doing
sudo killall system-config-services-mechanism.py
CPU usage went down to 30-35
