[Bug 98783] Re: MASTER: memory leak
Closing this one, since 1.10.1 in natty has all the memleaks fixed that were found with analyzer tools. When the Xorg process shows taking a lot of memory, it's usually a rogue client or the display driver leaking, and the xserver is caching pixmap memory. This is not a bug in the xserver, and should be filed against the client or the driver. ** Changed in: xorg-server (Ubuntu) Status: Incomplete = Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/98783 Title: MASTER: memory leak -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi, I've tried lucid a couple of days and Xorg is using about 240-270MB virtual memory (120-140MB resident), which is much better than the 1.5GB it used on karmic, but I'm not sure if the bug is fixed, or whether I just need to run it a while longer.

Just adding my two cents to the party... I've also been noticing excessive RAM usage in Xorg, having spent several weeks dealing with it - I've narrowed it down to the wallpaper- tray app I was running, also happens with Drapes (i.e. - when the wall paper changes frequently). Since having settled on a wallpaper, Xorg looks like such: 1673 root 20 0 160m 65m 21m R 10 1.7 13:30.42 Xorg As compared to having it eat as much as 1GB of ram after several hours of usage. I'm running Ubuntu 9.10 64bit, Nvidia 9800GTm with the proprietary 195.36 Beta drivers (also tested on the Official Nvidia drivers 190.53 with the same result).

[Bug 98783] Re: MASTER: memory leak
I only found this bug tonight - I don't want to seem impatient for a response :-) but I dug a bit deeper, and tried a series of different settings in xorg.conf. My ATI card (too old now for fglrx) using the radeon driver does offer some configuration options. I ultimately decided that --- with my 256MB RAM video card, and with X duplicating that size in virtual memory /twice/ --- that I'd try this Device-section setting: VideoRam128000 Now, /usr/bin/X starts up and uses about 400MB (at login prompt). When you login, it jumps to a bit over 500MB (running Compiz here) - that's 300 MB less than usual. I've tried 3d accelerated games on this laptop like the wonderful Penumbra trilogy) and they just don't cut it - so as long as I can function day-to-day in Compiz with my 'heavyweight' business/development apps, I'm ok this way. I'd like to understand why 2x the card RAM size needs to be allocated, though :-/Once my machine starts swapping, it gets ugly fairly quickly. Maybe this will help someone - and I'll still be watching for some solution to this issue.This is NOT windows, after all. :-) -- MASTER: memory leak https://bugs.launchpad.net/bugs/98783 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

Xorg's memory consumption goes up each time the tty is switched to or from the one running the X server, and each time the box is suspended resumed.

[Bug 98783] Re: MASTER: memory leak
X server resident memory usage went back up to 500MB and stayed that way even after I killed all GUI programs except the terminal and panel applets. Logged out and back in to restart X server. Usage went down to 200MB virtual and 69MB resident. Reloading firefox, and all my tabs, did not affect X server memory usage. Reading a document: ftp://ftp.ams.org/pub/tex/doc/amsfonts/amsfndoc.pdf (font heavy, since it describes a font) using okular caused X server resident memory to jump up to 200MB and virtual memory to increase by about the same amount. However, this memory was freed when I exited okular. Using evince to read the same document did not cause any increase in X server usage. xrestop is still reporting 17MB of usage.

Couple more remarks. I am using twinview on two 1600x1200 monitors. Shitwave flush is not installed. Well, actually it may be as it shows up on about:plugins but swfdec gets first dibs and it doesn't play flash without permission. And it doesn't get that very often. Particularly since it doesn't work on most sites, anyway. Running glxgears doesn't seem to change X server memory usage.

[Bug 98783] Re: MASTER: memory leak
After skimming through this 1300 page document with okular: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2798.pdf Memory usage went up and it did not go back down: PID USER PR NI VIRT RES SHR S %CPU %MEMTIME+ COMMAND 28137 root 20 0 379m 240m 14m S 0.3 24.4 3:22.85 Xorg I paged down through several hundred pages, some fast enough for the pages to be fully rendered, others not. Memory use went up early and then seemed to stabilize. Leading me to suspect that the bugs in okular are exciting the bugs in X. Someone else mentioned another document from this site and okular. Perhaps certain document excite the bugs in okular. This is a document I had been reading earlier. I opened the document again, and a curious thing happened.Resident memory went down while virtual memory went up. The resident portion then climbed back up again. When I exited okular the second time, the X server freed the memory. Restarted okular again. It resumed at the page I was at when I exited the last time.Virtual memory used by the X server almost instantly doubled from 200MB to 400MB, I think. Went back down again to near its initial value, then climbed back up to 368MB/230MB as a paged down.Went back down to 200MB when I exited the program. Rinse, lather, repeat. X virtual memory usage goes up to about 360MB when actively using okular on this document.Frequently goes down to normal when I exit. Loaded n1256.pdf from the same website. X Virtual memory climbed to 366MB.After page down about 40 pages, it suddenly dropped to around 200MB. But then it climbed again to 366Mb.So, okular likes to use about 160MB of server memory when it is running. I then opened both documents simultaneously in two instances of okular.X virtual memory went up to about 379MB, then stayed there, even actively paging through both documents.So okular seems to share its memory allocation between instances (two separate processes).Exited both and the memory usage did not go back down much, it stayed at 342MB virtual/201MB resident. Reloaded both documents individually and memory didn't go back down. Even after exiting the program again. But memory didn't go up much paging the documents, indicating that okular is still reusing the memory. xrestop, incorrectly shows that okular is using about 40MB. It seems like okular does some peculiar sharing of pixmap usage between processes.And when more than one is running, it may get a little confused about freeing it when it exits. http://www.open-std.org/jtc1/sc22/WG14/www/docs/n1256.pdf These documents are the C99 and C++ standards drafts. So, looks like the problem is somewhat reproducible. -- MASTER: memory leak https://bugs.launchpad.net/bugs/98783 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 98783] Re: MASTER: memory leak
This problem is reminiscent of similar problems with shmget(). You could either create a private shared memory segment, in which case you could only share it with subprocesses, or you created a public one. If you created a public one, it was not automatically deleted when your process exited or when the last process sharing the segment exited. At least there, you could run a utility program to clean up. Sure enough, the semantics of XShmCreatePixmap and XShmCreatePixmap look similar, but less documented regarding cleanup and with no utility. http://www.xfree86.org/current/mit-shm.html However, these shared memory segments are allocated using shmget(). I checked, and okular's Xshm does not show up in ipcs. KSharedPixmaps exist only on the server, implying the server creates them, not the client. And no shmget() would be expected to be used because applications share a common X server. http://api.kde.org/2.2-api/classref/kdeui/KSharedPixmap.html http://developer.kde.org/documentation/library/3.1-api/kdeui/html/ksharedpixmap_8cpp-source.html It uses XInternAtom and XConvertSelection It appears to create a selection named KDESHPIXMAP:xx xlsatoms doesn't show any such atom names. OpenGL may have its own pixmap sharing mechanisms. I still suspect this is a shared pixmap issue, though I haven't found the specific shared pixmap mechanism in use. I see this as the intersection of a number of bugs: - X or OpenGL failure to implement reference counting, close on last client exit semantics or incorrect implementation. - X or OpenGL failure to provide utilities to list and destroy orphaned shared pixmaps - xrestop failure to account for shared pixmaps - Okular - improper freeing of shared resources - X server/utils failure to identify application which created each retained resource. Looks like yet another case of bugs compounded by other bugs. If even one module had been implemented correctly, the problem either would not occur or there would at least be a workaround that would help you clean up the mess or identify the culpret. I do think I have collected enough information that this can be reproduced (with low but practical probability) and that it can be escalated upstream to nvidia AND okular. Even if the problem can't be reproduced on a particular machine, it appears that it is related to okular shared pixmap storage on the server and that can be analyzed. Okular probably isn't the only app which has this problem, but it is one that is known to have this problem. And it is not just an Okular bug since the X server allows applications to create messes that outlive the application and doesn't provide a way for the user to identify the application causing the problem and to clean up the mess. -- MASTER: memory leak https://bugs.launchpad.net/bugs/98783 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 98783] Re: MASTER: memory leak
A few lines from strace may be of interest, though strace bombs out pretty
early.
It suggests okular is using the MIT-SHM extension for something, though if that
were the problem the memory would show up in ipcs and would show up as shared
memory in top. I think the problem is in server side allocated shared memory

[Bug 98783] Re: MASTER: memory leak
The X server was eating around 500MB, almost half my system memory. I was able to reduce that by about half by killing and restarting firefox, killing okular, killing oocalc, changing system - preferences - appearance - no effects, killing compiz-decorator. As to the theory that it isn't a memory leak but instead just X holding pixmaps, I have some numbers that disagree. Notice the huge discrepancy between total memory reported by top and total memory reported by xrestop. Sure, I got rid of a lot of pixmaps by killing some applications. But the xserver is only able to account for 17MB of 258MB of usage. top: PID USER PR NI VIRT RES SHR S %CPU %MEMTIME+ COMMAND 4199 root 20 0 1231m 266m 8948 S 1.3 27.0 744:38.61 Xorg xrestop xrestop - Display: :0.0 Monitoring 54 clients.

[Bug 98783] Re: MASTER: memory leak
I just found a way to easily increase memory consumption for X.org. This works at least on two machines, a desktop and a notebook, with intrepid and KDE 4.2.2. Both machines have a NVidia card (Quatro NVS-290 and GeForce Go 7400) and I tried it with both the nv and the newest nvidia driver with the same result. Open okular with a very big file. Now you can see memory usage of X rising just by scrolling through the document. After going through 200-300 pages X needs around 1GB of memory. Sometimes the memory got released after closing okular but most of the time the amount of memory was just lost. I have tried this with a big djvu and a different pdf file with the same result. Using acroread for the pdf file, no increase in memory consumption can be observed. Hopefully this very annoying bug can be solved soon... -- MASTER: memory leak https://bugs.launchpad.net/bugs/98783 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 98783] Re: MASTER: memory leak
Another data point. I'm having the same overall issue using the radeonhd driver on my laptop, so there may or may not really be an issue with leaks in the nvidia driver. It sure seems to be related to firefox and flash content as the memory usage of the xorg process ramps up when I run firefox (1.5.x thru 3.0.5) and ramps up exponentially faster for pages that have flash content. Killing/quiting firefox frees up a lot of memory, but not from Xorg's overall total. It has behaved like this (for me) for the past couple of years. Only reason it's not a big deal for me is I'm constantly having suspend/resume issues since the 7.10 release, so uptime never exceeds a couple of weeks anymore. :( -- MASTER: memory leak https://bugs.launchpad.net/bugs/98783 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

It really must be firefox + flash. My firefox on x86 recently also acquired about 1.5GB of RAM with the X server running at more than 2GB. Killing the firefox instance also released quite a lot of RAM from the X server. But more importantly: As reported earlier, I don't have the problem on my amd64 desktop at work. And guess what! I don't have a flash plugin running for my firefox there. So please debugger folks. Test along these lines, and I am almost certain you will find the real cause of this.

Like Francisco, my Xrestop also looks fairly 'normal', and closing firefox doesn't change more than at most a couple of meg of ram. Its a pretty annoying bug because it forces me to restart ubuntu every day, or wave goodbye to a couple hundred meg of ram.

while knowing very little about X, I think in general, it would be nice if pixmaps were associated with the process that requested them (maybe by just having the process associate a constant label with the pixmaps it uses). then it would be possible to write a utility named pixmaptop and also to cleanup pixmaps (even if not automatically, at least manually), and also to have something like sar to show usage trends (memory leaks) -- MASTER: memory leak https://bugs.launchpad.net/bugs/98783 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

Re: [Bug 98783] Re: MASTER: memory leak
The problem is that the people that can work on the problem think that there is no problem, since measuring memory use is not something easy, and any badly written app (typically it was flashplayer, but I already tried disabling it) can leak pixmem. So until somebody of us identify which is the culprit, and it can be different for any of us, there's no way this is going to be solved. The fact is that now my X server is using ~300m and if I quit the session (all X programs except gdm), it will still be using almost all that memory, go figure. Now, you say that with another graphics card you don't have the same problem, maybe that is the root of all evil, are you using the same version of the nvidia driver? Most reports have been with nVidia, and since some of the reports are false positives it may well be a driver problem. -- MASTER: memory leak https://bugs.launchpad.net/bugs/98783 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
