Surges of extremely high CPU usage, application agnostic
For about 2-3 weeks, I've been noticing some serious bog on my system, and can't seem to figure out the cause. Here's some possibly relevant details:
- Uname:
Linux bigBang 3.11.5-1-ARCH #1 SMP PREEMPT Mon Oct 14 08:31:43 CEST 2013 x86_64 GNU/Linux- Running standard Arch kernel.
- Nvidia Quadro FX 1800M with the nvidia driver from extra.
- Openbox, feh for background creation, three instances of conky, tint2 as my panel/tray/bar, and wicd for internet
- Disk utilization:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/root 30104556 14245392 14306884 50% /

Please let me know if there are any other details that would help. I'll leave it at that for now and move onto the observations. It doesn't seem to matter which application I have open when this happens. Typically, I'll notice it when chromium is open, and then pop open top to verify... but then top is shown as eating ~50-100% CPU. Then I'll close Chromium and it'll die down a bit, but top will stay high. I thought I'd try switching to jumanji in the event that it was a chromium issue I was experiencing. Then jumanji bogged (with chromium now closed). I cycled through with emacs and pcmanfm to show that it really doesn't seem to matter -- something is bottle necking and any application (including just X) that's open starts registering as 100% of CPU. Then magically, it will just stop doing that and I can open whatever I want with no issues.
This is on an HP 8540w Elitebook with an i7 and 8GB of RAM. I really wouldn't expect a single application to be doing this. I would have posted screenshots but completeyl borked an imagemagick command and resized the originals; I'll have to wait until it happens again to post the shots of top that I intended. Nothing appeared out of the ordinary to me; just whatever application I opened zoomed to 50-100+% of CPU.
Suggestions to debug or the best log to check? Any ideas on what kind of application or activity or setting would cause something like this (intermittent bogging)? I have a couple of cronjob scripts that run, but they're extremely simple like running an emacs shell command and cat-ing out a file to put on my background with conky. I'm going to see if this bogging happens at any particular time to see if it corresponds at all with cron or some other service that runs or does something.
Thanks for any help!

Re: Surges of extremely high CPU usage, application agnostic
You can write top output to a file, instead of taking a screenshot, using this command:
top -b -n 1 > filenameOffline

Re: Surges of extremely high CPU usage, application agnostic
@Bandit: thanks for that -- I'll wait until it happens again and then do that a few times to capture.
Still open to whether or not top is the best way to debug this issue. Like I said, it's application agnostic -- whatever I open eats 100% of the CPU whether one would intuitively think it's a resource hungry app or not -- chromium, jumanji, top itself, X, emacs, pcmanfm. They all do it when opened. I believe the problem is elsewhere and the CPU is simply having a tough time keeping up with anything. It's the kind of behavior I'd expect if something was writing to disk constantly or swapping or something (though I have no swap partition/file).
So... I'll definitely take the suggestion, but if passer-bys can provide other places to check, I'd love to do so as top only seems to tell me that my CPU is churning, not why...

Re: Surges of extremely high CPU usage, application agnostic
Okay, grabbed some top output, which I'll post. At first I was limiting it to 20 lines as I thought that should be sufficient, but then stopped adding that option in case there would be something of interest further down.
Chromium starts bogging

Whatever was happening is done now, and watching top and starting thunar, jumanji, geeqie, or whatever else at most ramps the CPU to ~10% for a split second and then it's beck down to 1% or less. I even just started gimp and the CPU only went up to ~30% for a couple of seconds. Here's my system now that the CPU vampire is gone, running 10 Chromium tabs, jumanji, thunar, geeqie, jumanji, and gimp open:

Re: Surges of extremely high CPU usage, application agnostic
I think the problem may be in nvidia driver or rather combination kernel 3.11.x and nvidia 325.15 (which doesn't support 3.11 officially).
You can try installing nvidia beta, Nouveau, lts kernel (3.10) or even better see if without starting xorg the problem is still there.

Re: Surges of extremely high CPU usage, application agnostic
@einhard: Ah, fantastic to know. Thanks so much for chiming in. I'll probably try Nouveau as I think I need X, but I might be able to rock some non-X work. The problem is that it is so unpredictable. I seem to notice it the most in Chromium, but then after I quit out of it, it persists for a really long time and I can't figure out what the issue is. Nvidia makes more sense to me because it's just this sort of "background thing" that's always going on and would explain a potential bottleneck affecting all applications vs. something in particular.
Thanks!

Re: Surges of extremely high CPU usage, application agnostic
Hmmm. Not thinking that's it, at least if installing linux-lts and nvidia-lts is supposed to work?
$ uname -a
Linux bigBang 3.10.17-1-lts #1 SMP Sat Oct 19 08:41:40 CEST 2013 x86_64 GNU/Linux
$ pacman -Q |grep nvidia
nvidia 325.15-10
nvidia-libgl 325.15-1
nvidia-lts 325.15-7
nvidia-utils 325.15-1
$ ls /usr/lib/modules/extramodules-3.10-lts/kernel/drivers/video/
nvidia.ko.gzUnless I didn't use nvidia correctly for the linux-lts kernel? In any case, if it's a conflict between nvidia and kernels >= 3.11... that doesn't seem to be my issue as the CPU is crazy high right now with similar output to the top results posted above. Whichever application I start, the CPU load soars to anywhere between 30-200% (chromium, evince, jumanji, thunar, top, and even conky pops up at 30-50% sometimes).
Still working on nouveau, but having issues as posted about here
