[Bug 343714] Re: Kubuntu Jaunty KDE 4.2 very high memory usage
This bug report has been inactive for quite some time and in the meantime Ubuntu has moved along. I hope the reported problem has been resolved in the current version of Ubuntu. If it has not and there are people willing to follow up with information collecting and testing, it is best to file a new bug report with the latest Ubuntu development version (currently 10.04, but soon 10.10), using the ubuntu-bug command if possible. Feel free to mention the bug number of this bug. We are sorry that we are not always have the capacity to look at all reported bugs in a timely manner. Occationally we have to purge old bug reports where no progress has been made, whether it is due to reporter not being able to respond or lack of manpower on the Ubuntu side, in order to keep our list of active bugs current. Sorry for the inconvenience this may cause. Here are a few tips that will increase the chances that your bug gets priority: * Read https://wiki.ubuntu.com/X/Reporting * Browse https://wiki.ubuntu.com/X and see if there is some relevant information for you problem * Respond quickly to questions from triagers * Try changing things to see if the behaviour changes, e.g. * A new mainline kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=M;O=D (more information at https://wiki.ubuntu.com/KernelTeam/MainlineBuilds) * The xorg-edgers PPA: https://launchpad.net/~xorg-edgers/+archive/ppa * Various options in `/etc/X11/xorg.conf` (see `man intel`) * Browse other bug reports to see if you find a similar one and provide the information that is being asked for there. -- Kubuntu Jaunty KDE 4.2 very high memory usage https://bugs.launchpad.net/bugs/343714 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help. It seems likely to me this bug is gone; the -intel driver has improved immensely in Karmic and a lot of bugs are being reported as no longer present.

[This is an automatic notification.] A new major version of the -intel driver is now available in Karmic. This version includes a major reworking of the acceleration architecture, which resolves a huge number of issues. We do not know whether it resolves the issue you reported. Would you mind testing Karmic Alpha-2 and seeing if it is still a problem? CD ISO images are available here: http://cdimages.ubuntu.com/releases/karmic/ If the issue can still be reproduced on karmic, please report here with your findings, and attach a fresh Xorg.0.log from your test, and we will be able to forward the bug upstream. Otherwise, if the bug no longer exists in Karmic, let us know that as well.

Here's what solved the swap growth issue for me: (Not sure if its related but might help someone).

That's when I noticed the swap growth but didn't think they were related at all. http://ubuntuforums.org/showthread.php?t=1130582 After googling around I found UXA has some major memory leaks which could cause swap growth. https://bugs.launchpad.net/ubuntu/jaunty/+source/xserver-xorg-video-intel/+bug/359392/comments/517 I Switched back to EXA (only changing xorg.conf but still with driver upgrades and patch scripts), and that resolved my issues.

Now, after about 6 hours of use my System Monitor shows 38% memory in use by programs and 61% in use as cache. We also have Ubuntu 9.04 on a Netbook with 1.5gb of RAM, and it doesn't seem to have the same problem, although it is not used heavily (mostly just a program or two open at a time). I just ran a test on another computer we have in the house with 2gb RAM and Jaunty recently installed. It also shows the cache memory climbing with each application opened, especially KDE apps, although I only tested it for a while, and did not get it over about 50% combined program RAM and Cache RAM.

I see the problem also without Firefox. And the problem seems not to be related to a heavy RAM usage: it start swappin even with far less than a GB of MEM used (on a 2GB RAM machine). Maybe the problem is related to the management of cached memory: I'll try to better understand if this is the case, but let me say that just now my current MEM breakdown is 1.35GB cached, plus 541MB used (and just 6MB buffered) and the disk swap usage is 500MB which seems quite a lot to me, with only 550MB physical mem used...

Even without swap partition mounted the system crashed. Coming back with atop, it turns out that it was willing to write to a swap partition anyway (and I guess it crashed because there is no partition available just like it was crashing when the partition was there but it was full). This (*) is an example of what atop says for the period when the system crashed. This means that the system would like to commit 2.2GB of virtual memory (vmcom) having 0.0MB of swap partition (SWP tot) and a vmlim of 1.0GB (from man atop I read that 'vmlim' is by default swap size plus 50% of memory size, and that the committed space is the reserved virtual space for all allocations of private memory space for processes. The kernel only verifies whether the committed space exceeds the limit if strict overcommit handling is configured (i.e. if vm.overcommit_memory is 2, but in my case it is 0).

[Bug 343714] Re: Kubuntu Jaunty KDE 4.2 very high memory usage
The first screenshot does not show Firefox at all. Is there a reason for this or are they 2 separate issues. there is a bug on both we need to find out what one it is. I'm away from home all day today and tomorrow, I dont have access to my system with the bugs on it so i cant give report numbers at this time. -- Kubuntu Jaunty KDE 4.2 very high memory usage https://bugs.launchpad.net/bugs/343714 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 343714] Re: Kubuntu Jaunty KDE 4.2 very high memory usage
The first screenshot was to show the memory usage, immediately after reboot/login, without opening any applications. So, this probably looks like two separate issues. Please let me know what other information is needed to investigate, and I ll provide them as soon as I can.

Looks like Firefox is using a ton of memory. ** Changed in: firefox-3.0 (Ubuntu) Sourcepackagename: kdebase-workspace = firefox-3.0 -- Kubuntu Jaunty KDE 4.2 very high memory usage https://bugs.launchpad.net/bugs/343714 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdebase-workspace in ubuntu. -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs

Is there any application in particular that uses a lot? The apps I can see in top all look normal. ** Changed in: kdebase-workspace (Ubuntu) Status: New = Incomplete -- Kubuntu Jaunty KDE 4.2 very high memory usage https://bugs.launchpad.net/bugs/343714 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdebase-workspace in ubuntu. -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
[Bug 343714] Re: Kubuntu Jaunty KDE 4.2 very high memory usage
Unless I restart every day, I find the system very sluggish in terms of performance. Looks like some memory leak or something, but I don't know how to find out what applications are causing the same. Currently I have only firefox/dolphin/konsole/kate opened, but the usage shows that the entire 2 GB main memory and nearly 1 GB of swap is used !! and I find even typing this comment itself slightly unresponsive sometimes. Could you please help me find out which applications are causing this problem? I don't how much memory each application is supposed to take. $ free total used free sharedbuffers cached Mem: 20536442001740 51904 0 68401225048 -/+ buffers/cache: 7698521283792 Swap: 1726948 905276 821672 $ uptime 02:55:55 up 8:11, 1 user, load average: 0.14, 0.29, 0.34 I am attaching the output of 'ps -ewo cmd,rsz,vsz --sort -rsz,-vsz' (all size in kb).
