Software :: Software To Kill CPU Hogs?
Aug 2, 2010
Does software exist that does the following? Monitor processes and rank by CPU usage, as top does. Flag excessive CPU usage by individual processes, using rules and queries to a database of previous offenders. Offer a configurable setup to automatically terminate CPU hogs under certain circumstances. Might include replacing displayed browser pages with a notification screen. Add incident report to database for each offense. My personal favorite is Flash, which hides behind 'nspluginviewer'. It keeps my CPU warm even when it is not displaying anything. That heat equals wasted energy. Multiply that by the millions (probably billions) of computers worldwide that have sleeping Flash players running on them right now, and that equals a lot of wasted energy. Probably a coal-fired powerplant or two worth of wasted energy.

Don't know how to report to bugzilla, but first of all I want to know if it's only my PC or if you have this problem too. Today I started copy a 1.4 GByte from an internal disk (NTFS formatted) to a USB stick. The process is extremely slow (but this isn't a news, it always was with previous Fedora versions), in the meanwhile I tried to start Firefox and I found that it doesn't start: from KDE system monitor I see that Firefox starts loading but it blocks in "waiting for disk". Tried with some other program (Ksnapshot, Filezilla) and they're also extremely slow in loading when copy is active. When putting the copy process in pause, after some time programs starts opening.

I tried upgrading today from VirtualBox 3.1 to 3.2 (VirtualBox-3.2-3.2.0_61806_openSUSE111-1.x86_64.rpm) on my openSUSE 11.2 system and it's not cooperating. The installation itself went fine, but as soon as I try to start a guest, the VirtualBox process ramps up to 100% and stays there until I poweroff the guest. The guest itself is VERY slow. These guests worked fine on 3.1.
For example, if I start an openSUSE guest and stop the Grub counter, therefore leaving the screen at the Grub bootloader, the VirtualBox process remains at 100% forever, without any activity on the guest.I also have a Windows guest and it has the same problem.
I can obviously try downgrading again to 3.1, but I was hoping that someone else has run into this issue and knows what to do about it.

the process is mcelog. When I do as root kill -9 2323 which is pid of mcelog the process is not killed. I tried doing the same from top, press K and enter pid of mcelog. doing ps auwx | grep mcelog I see there are several results. I tried killing all of them like kill -9 2355 2341 3425 2345. But re-running the above commands still shows them as running. How else would I troubleshoot this to avoid restarting of the box.

I dual boot windows and ubuntu, and fount it very nice. But when i run flash game at my chrome, i can see the CPU usage increase a lot. When it reaches max, the flash game will be 'flashing' and lag. I use latest stable google chrome and flash player. Any idea how to fix this? I encounter no problem when playing at Windows.

Dell Inspiron 1427
Core2Duo T6400
Nvidia Geforce 9300m gs

Freshly installed and updated Ubuntu 10, the first thing I did was install Wine and the second was installed Steam under Wine. Steam will run, but the moment it opens, xorg's CPU usage jumps to around 70% and stays there. Graphics card is an old ATI Radeon 9600 pro.

I'll often run iceweasel for watching videos via flash (hulu, ....., et cetera) while working, in fedora I never noticed any performance problems, watching the video while using chrome for browsing, gedit for editing, et cetera, everything was responsive. Though, now on debian running iceweasel for the same purpose hogs memory and processor time, which slows down the responsiveness of the system as a whole, making it difficult to use other programs.I'm curious how I should go about troubleshooting this issue, and what diagnostics might help me find the solution.

My configuration is OpenSuSE 11.4/KDE4/32bit. I am noticing that for about 20 minutes (or more) after first login every time there is a process which takes 100% CPU for most of the time and, of course, slows everything down. The system monitor suggests it is the 'tracker-miner' process (whatever that is). Do I need the tracker-miner? What good does it do? Is there any way to stop it (not to start it)?

Since the OpenOffice quickstarter effectively disables the shutdown and hibernate buttons under Lucid, I put a command into my .logout to kill the quickstarter:
Code:
kill `ps aux | awk '/soffice.bin/ && (/quickstart/ || /splash-pipe/) {print $2}'`
This works fine if I execute it manually, but in the .logout file it seems to have no effect.

I accidentally submitted a print job twice. So I have this job sitting in the queue and haven't been able to figure out how to clear it. Tried system > administration > printing. Nothing there about how to clear the queue. I'm running 8.04.

Sometimes I find a process named 'sh' running under my username with the status 'zombie' waiting channel 'do_exit' on my system. Its ID increments by 4 every time System Monitor updates its display.
Today, it was there immediately after booting The only thing I did after logging in is start the System Monitor
I can't kill it since its ID changes too fast.
I don't know how it gets started, but it bothers me since it is behavior I would expect from something that is trying to hide.
If I hover over its name, the tool tip contains 'sh'

I have this problem where I keep losing internet and the only way to fix is to restart the computer, I think it's because my wifi card isn't completely compatible with ndiswrapper. Anyways when ever this happens I am unable to shutdown properly because ubuntu says firefox-bin is still running, when I try to shutdown it just hangs. I tried killing firefox-bin with the system monitor but that didn't work, then I tried killing it the terminal by using killall -9 firefox-bin. This too doesn't work. How can I kill firefox-bin?

Sometimes (rarely) when I try to open VLC it wont open, but it stays in the background and takes 98-100% of one core.
The problem is that I can't kill that vlc-process.
Code: Select allkillall vlc
will NOT kill it
and
Code: Select allkill 31641
won't work either
top shows
Code: Select allPID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
31641 xxxxxxxx 20 0 1320248 64384 39120 S 100.0 1.6 44:51.94 vlc
Is there any way to kill the vlc-process (without booting the machine)? I also tried the "killall vlc" and "kill 31641" as root with the same results.
I have Debian jessie and the only "nonofficial" repositories I have enabled are
#google chrome
http://dl.google.com/linux/chrome/deb stable main
#Backports
deb http://httpredir.debian.org/debian jessie-backports main
And from those I have installed only chrome, and wine-development, and I dont think those could have anything to do with this problem.
Booting the machine does work, but I don't want to boot my machine just now. This happens about once per week

OK, I admit I'm a little OCD about icon placement on the Desktop - I want to do it myself - so this is driving me a bit nuts.I have right-clicked to disable the option 'keep aligned'. I have made sure it is disabled in gconf-editor. BUT IT KEEPS COMING BACK!ince I don't mess a lot with my desktop, I'll notice it's reverted when I add something new, can't place it exactly where I want to and once again have to untick 'keep aligned'.It seems to be random so not quite sure what might be triggering it.

Ctrl-c doesn't always work to kill the current process (for instance, if that process is busy in certain network operations). In that case, you just see "^C" by your cursor, and can't do much else.What's the easiest way to force that process to die now without losing my terminal?
Summary of answers below:Usually, you can Ctrl-z to put the process to sleep, and then do "kill -9 process-pid", where you find the process's pid with 'ps' and other tools.On Bash (and possibly other shells) you can do "kill -9 %1" (or '%N' in general) which is easier. If Ctrl-z doesn't work, you'll have to open another terminal and kill from there.

On Xubuntu Lucid, How do I kill Xfce's desktop (xfdesktop) without it restarting almost immediately? Right now, when I kill it (using built-in kill; /bin/kill; pkill) it restarts. I don't want that. Xfce seems to no longer have the option to choose if I want a desktop or not.

I have an issue on one of my servers whereby the [normally very helpful] du and tar programs are somehow using up too much or my system resources (du 40% mem, tar 20% mem) and causing problems. I am after a command which is able to kill a process without knowledge of a PID but by process name e.g. "du" and memory usage e.g. >= 10%.
Something along the lines of:
kill $(pgrep du) grep %MEM > 10
Although I know that is invalid syntax I cannot fathom the correct/best way to achieve this end!
