My CPU is acting strange

mag1strate · 08-25-2009, 11:22 PM

I am using fedora 11, and in a previous thread I was told how to use the top command in the terminal, but I must have done something b/c now my processor is acting really strange and maxing out some of my cores when nothing else is running in the background! Can any of you guys help? I shall place the top results now. Thank you for your time!

Looks like you have two instances of top running. They may be racing each other.

mag1strate · 08-26-2009, 06:18 AM

But one of the times it was overloading with firefox, is there a way that I can kill the process?

kdelover · 08-26-2009, 08:12 AM

In top press K and give the PID of that process and the relevant signal 9\15 and kill it.

mag1strate · 08-26-2009, 09:55 AM

im sorry but could you show me an example? like do i just press k, then a number 9-15 then I type in the name or what do I do?

kdelover · 08-26-2009, 09:58 AM

start TOP & press K ,when you do that it would ask you PID to KILL,enter the PID ( process ID ) you see hit enter and it would ask you for the signal to send ,by default it would select 15 ,select what ever you want 9 or 15

and hit enter.

Or you can even do ps -ef | grep -i "firefox" and then get the PID and kill it with killall command

or do pgrep firefox and kill it with kill command

Or pkill -9 firefox

mag1strate · 08-26-2009, 02:56 PM

Wow thank you very much!

kdelover · 08-26-2009, 03:09 PM

one more,if you want to kill all the process owned by a user kill -9 echo $(lsof -t -u <username>) or pkill -u <username>

chrism01 · 08-26-2009, 06:10 PM

I also recommend

top -u <username>

to cut down num procs shown to a manageable number
