Last time I saw this was a dieing drive. Run hdparm, and maybe smartd. A lot of times you can be convinced its ok because something you use rarely will occupy the bad sectors.

Thanks, I should have mentioned the disk hardware. The system (root) is on sda2 and sdg2, /home is on sda3 and sdg3, both in btrfs raid1 configuration. The disks are less than a year old. SMART gives the following: Monitoring 2 ATA and 0 SCSI devices Device: /dev/sda [SAT], opened ATA device Device: /dev/sda [SAT], previous self-test completed without error Device: /dev/sdg [SAT], opened ATA device Device: /dev/sdg [SAT], previous self-test completed without error [...] Started with '-q onecheck' option.

There are a number of issues that might come into play, but it all gets back to the fact that Linux is not a Real Time Operating System with a guaranteed response time. While it is possible to configure stock Linux to do a good job in that area, it also requires making sure that the right application are used, that the hardware performs properly and more. As John points out, dying disks can produce this phenomena; anything that eats time in the kernel, spin loops, waiting for events, means user level processing isn't being done. I once wrote a disk driver for V7 UNIX that did bad sector handling in the kernel. On poor reads it re-read, perhaps used the checksum to try error correction. Oh, it worked, it worked well, but all that was done in the kernel with interrupts turned off! That mouse events, a very high priority, still respond, means your machine isn't dead :-) I can repeat this phenomena. If I'm in eBay and visit a site and using Firefox, and click items to open them in a background tab, and do this a lot, then suddenly the machine freezes. If I kill Firefox the machine comes back. if, during that, I hot key out of X/KDE to a VT running root and use 'w' or 'top' I see I have a load factor of 10 ...1 ..12. 15...20 ...25 YIKES And I see that the amount of swap being used is rising ... Rising Conclusion: FF has a memory leak. Well actually on close examination, opening just one or two tabs, I see that it isn't actually FF but rather a plugin -- its the 'plugin container' that is at the top of the list showing excessive CPU consumption. I suspect that it might be associated with displaying an animation, graphic or possibly an embedded video/animation. We can. Perhaps, blame any oen f a number of well known plugins for this :-0 The other occurrence seems to be with the dreaded LinkedIn. I get pop-ups telling me that a JavaScript isn't responding. What it means is that its in a spin loop of some kind. In short, what we have is complex programs interacting in strange ways. The great power of UNIX of the 1970s era, what made it revolutionary compared to the mainframe applications of the day, was that it was made up of short lived, small programs that were strung togehter with poles and scripting. By comparison, the mainframes were running things like CICS which were so enormous, so complex that they did all their database and teleprocessing internally. One huge address space. It grew so complex that IBM had to come up with a way of extending the address space so as to accommodate it! UNIX of the 1970s era was roll-in/roll-out not virtual memory. back then we said "Virtual memory means virtual performance". Memory was !expensive! Realistically, an application had about 56K of memory MAX. It produced a particular discipline of programm ing that we don't seem to have today. Some intermediate era GUI front ends were just that, perhaps a shell script that used termcap/terminfo and like the CLI shell scripts of old ran processes to do the work and filtered the results for display. These were still 'slim'. The work was not in the GUI. Along the way we had the intermediate of Tk, with Perl or some other scripting language that was more capable that the traditional shell. You could do a lot with Perl, but you still made calls to regular programs to do specific work. But once you reach a certain level of sophistication things have to be dragged into the GUI body, and once that threshold is passed then programmers naturally work that way. It might be possible to write a mail UI in Perl/Tk that makes use of many external programs. You may even be happier using your favourite editor for message composition :-) Heck, the Thunderbird 'enigmail' plug-in does use an external OpenPGP application. But the gVIM spell checker is .... Lets face it, clunky. See http://emailproject.perl.org/ http://www.perl.com/pub/2004/06/10/email.html http://perlcomposer.sourceforge.net/ https://glade.gnome.org/ I don't know of an off-the-shelf Perl based email GUI or one for browsing the web. I'm not familiar with Python. The real enemy here is complexity. It the enemy of security, traditionally, and if you count the 'availability' aspect of security http://en.wikipedia.org/wiki/Information_security#Availability then its 'in scope'. As i said, what made UNIX revolutionary was that it broke away from the idea that a program had to encompass everything on one address space with all the threads and interactions etc which came with that approach. We seem to have rescinded this paradigm shift. We are paying the price. We are justifying it on the alter of 'performance'. Personally I think our edifice is too high (or deep) When I look at what it took in V7 for a character being typed on the keyboard to being echoed on the screen, and I look at what it takes to do the same using KDE (or gnome or even LXDE or e16 or xfce) I'm amazed. X was, is, just so comprehensive, so far reaching, that it astounding it works at all. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Can you still switch virtual terminals? Ctrl-Alt-F1, for example? Often that still works when a system is "frozen" as the system is not frozen - the DE is frozen. If so log in on tty1, run top, and go back to the DE and start working. Then when it freezes pop back to tty1 and see what is what? Might be informative, might not.

Hmmmm. A 5 to 60 second free is not an RTOS issue; some hardware or software in the system is a problem.

Yep, the first part is to figure out what is actually "frozen".

I can still, manually, kill firefox from a root login at a VT. But it would be nice to have firefox running, as you say, in a container that limited how much memory, or CPU it can have. I'd happily put up wuth FF alone 'freezing' so long as it didn't drag down the rest of the system. I think a few here would agree on that. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Ultimately we are saying the same thing here. I've dealt with RTOS in avionics and other industrial control applications and the DISCIPLINE surrounding the hardware and software is part of what guarantees the response. Commercial off the shelf and 'white box' equipment isn't spec'd the same way that RTOS grade equipment is. Desktop Linux might be tuned to be more responsive to interactive events than the server model, but there is still no guarantees. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

We are using 'modular' in two different senses here. You are using 'modular' in the sense of 'structured software', thank you Ed Yourdon and many others. I am using 'modular' in the sense of discrete programs running in separate address spaces communicating using defined protocols over defined communication channels, the separation being enforced by the simple fact that they are not resident in the computer memory at the same time. And that being a roll-in/roll-out model not a virtual memory mapping model. I'm not questioning the 'modular' construction of things like Gnome. I am questioning what amounts to the call-tree and the combinatorial complexity of the execution path and how it all fits into one address space. The Yourdon model of modularity had a pretty strict 'tree' and issues about things like 'stubs'. Once we get into even-driven programming for things like Gnome and many GUI models, MVC and things like call-backs, we open a new can of worms in terms of complexity. All of a sudden 'modularity' has taken on a different meaning. Separate coding of things like 'plugins' that operate in the same address space are now 'modules. And we've all seen how that can produce problems in Firefox and Thunderbird: one of the basic debugging approaches there is to run with plugins disabled. Yes, "that was then, this is now". We have to deal with the "now", but the way we have built our "now" has replicated some of the problems I mentioned with CICS of old building too many functions into one megaprogram/address-space. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I think you're right about it being the Desktop Environment. The mouse cursor will move from side to side, but I cannot scroll the message pane in Thunderbird. I cannot switch between virtual desktops or open menus. But all this activity seems to get buffered, so when things come back to life, there is a flurry of activity as it catches up.

So even though gkrellm shows the increased number of processes, the lack of information on CPU usage, memory, swap etc is unreliable?

I had similar problems due to a bad contact between graphic card and motherboard. There must have been a little "crack" that opened when the card or the MB got too hot. I changed the card to another slot and that solved the problem for a year... ... then the card sometimes got very hot and "disappeared": I had to clean the fan of the card with a vacuum cleaner... ... finally firefox's inability to release memory of closed windows makes the system slow up to a "freeze" for a limited time, but opening next window leads to next temporary freeze. (I often work link lists of tumblr photo sites, opening the links in new windows. Each window adds memory, at 2 GB firefox gets notably slower, at 4 GB firefox gets almost unusable, at 6 or 7 GB the whole system begins to suffer...). The only "help" is to terminate all firefox processes.... -- Daniel Bauer photographer Basel Barcelona http://www.daniel-bauer.com room in Barcelona: https://www.airbnb.es/rooms/2416137 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The conditions under which that is helpful are limited. It may be that an application is asking the display layer that Xorg uses to do something pernicious. It may be that your video driver has a syndromic bug. So... What display hardware/driver do you use? If you use KDE, then systemsettings -> Desktop effects use the 'advanced' tab The first two options let you alter how the kwin layer works. openGL vs raster and Qt graphics being native or raster. Presumably similar exists for Gnome. I can't say what combination works for who/what/when. its a YMMV thing.

Interesting. I found I was using openGL 2.0. I changed this to openGL 3.1. Will report back after a suitable test interval.

I have re-installed opensuse entirely from the DVD (checked the DVD as well) and same issue. I never had this issue with my 9500GT at all, but now I can't use those 3 programs at all.

Interesting. I just tried launching GoogleEarth and can confirm that it freezes the system, with kwin_x11 running at 100% on one core. However, once GoogleEarth had loaded it was usable, with CPU usage dropping back to normal. The desktop then worked OK. But, when nothing appears to be amiss with the desktop GUI, if I then [Ctrl][Alt][F2], where I have htop running, it triggers kwin_x11 to use 100%. This continues until I do [Ctrl][Alt][F7] to get back to graphical mode, when CPU usage then drops back to normal (I have gkrellm running on the graphical desktop).

Recently a patch was added to kwin5, so that a bug related to freezes with nvidia graphics cards is resolved. Could you try updating to the latest kwin5 with fix_nvidia.patch?

I'd be happy to. Where do I find it, and how do I run it?

Try installing a package from here[1]. After installation, kill kwin_x11 and start the new one from a shell or krunner.

Is this patch available without having to install the KDE5 framework? -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Conclusion: FF has a memory leak.

If you use addblock (or similar), on certain pages the amount of used memory skyrockets. I remember reading about the issue. A certain sample web page could use gigabytes.

Well actually on close examination, opening just one or two tabs, I see that it isn't actually FF but rather a plugin -- its the 'plugin container' that is at the top of the list showing excessive CPU consumption. I suspect that it might be associated with displaying an animation, graphic or possibly an embedded video/animation. We can. Perhaps, blame any oen f a number of well known plugins for this :-0

Typically flash. That's why I block all flash with "flashblock", and only allow it on the pages or frames I want. It causes problems on youtube, though, when html5 and flash both compete to render the same video, and both fail. - -- Cheers / Saludos, Carlos E. R.
