Ubuntu :: Complete System Freezes When Using Torrents?
May 21, 2011
Beginning on the release day for Firefox 4, my system has been encountering hard freezes (no responsiveness to any key entry and only way to restart is by hitting the reset button). I had installed firefox 4 with no issue, but once it was open, it kept freezing my system. Some addons weren't supported anyways, so I uninstalled it and got back my 3.6. At the time I was using rtorrent, but within minutes of using it since the firefox install, my entire system freezes up.
Naturally I suspect HDD or RAM, but both have been extensively tested. Next I began browsing forums and found some tricks like turning off IPv6 or changing settings via HDPARM, but none have made any difference. I have moved on to using Transmission, and the problem still exists, but it occurs much less frequently.
I have also since then noticed that transfers of files from my 500GB OS/Torrent drive to my RAID 5 array and vice versa moves at 2-4MBytes/s, much too slow. So next I set up my torrent client to download directly to my RAID array, and lo and behold no freezes! Also, while transfering data the system moves at an absolute CRAWL, as in browser windows turning gray, saying that they have stopped responding, etc. I ran a fsck on my 500GB drive, which instantly told me my file system was clean. I'm at my whit's end here! I hate re-posting on a topic, but I feel like I've tried everything!
I'm experiencing complete system freezes when dowloading torrents with more than 800kb/sec (I think this is the limit, I've capped it at 750, and it seems to be running ok now). I had this same problem in Ubuntu aswell. But not in Win 7. The problem also appeared in ubuntu when streaming video through VLC with more than 800kbps.
As my connection gives me quite alot higher download speeds this kind of annoys me, and me being quite new to this whole Linux thing, don't really know what to do. I had a dialogue with someone at Ubuntuforums regarding this, but we pretty much got nowhere.
I have an odd issue that someone has hopefully seen before or can provide a next step. Firstly, I installed Ubuntu 9.04 about 7 months ago and things ran fine. I then did an upgrade (via apt-get) to the 9.10 kernel: Current: Linux 2.6.31-16-generic #53-Ubuntu SMP Tue Dec 8 04:02:15 UTC 2009 x86_64 GNU/Linux
Still, I had a properly functioning system. I then decided to install selinux since I was interested in learning how to set it up and get familiar with it's security features. When I was installing it, it got stuck on the portion where it had to modify Grub. It got stuck in a similar point as the following:
I removed windows completely from my Dell Inspiron N5010 and installed Ubuntu 10.04.1 64bit. In windows I have the option to create the system image of system's current state so that if something goes wrong I could easily restore my system using that image( I am not talking about windows Restore facility). I wanted to know that if there is something available in Ubuntu also. I cant use Dell recovery media creator as I have deleted recovery partition. I have already used Remastersys and it also did its job well but after restoring my Graphics card driver did not work well.
I get a complete system failure when my CPU is stressed. It's not the temperature because when it crashes the CPU temp is only ~55 C. When it crashes the video freezes but the sound repeats itself. Example. I start handbraking a movie, then open a tv show in VLC. This is what I hear.
Did you get that tire - then it freezes
get that tire get that tire get that tire get that tire ... etc
That continues until I reboot my computer. This crash is pretty reliable, as every time I load my CPU that happens. If I don't do anything CPU intensive, I don't get the crash. Also, if I only load up one core of my CPU, then everything is fine. However if I run something such as prime95 or handbrake (which both utilize all 4 of my cores) the computer will crash within 30 seconds.

I'm on ubuntu 10.04, and pretty new to it - over the last 2 weeks I've done probably 10+ fresh installs due to me not knowing the system, trying things. I looked for a way to back it up and found this guide - [URL]. When I use the feature as listet, it doesn't exclude the folders, and the system is "almost" the same as pre-recovery - and I'm copy/pasting. Is there a way to make a COMPLETE replica of my system, that I can launch when failed, so that - it's back to when I was "ok".. like all programs install post-copy to be gone..
My laptop running Ubuntu 10.10 had suddenly go to a dark gray screen that will not take any kind of input other than holding to power button down for 5 seconds. I'm not running any new or odd programs just Firefox, Openofice writer, and Pidgin. When I turn the computer back on I do not see any kind of an error message. I'm looking for any advice that will help me find the cause of the problem.
Since having installed Lucid Lynx, I have several complete system crashes a day, no matter which applications I am using. Lucid crashes without any error message and the system reboots. I have had no problem whatsoever with Karmic Koala (also switched from ext2 to ext4 when installing Lucid Lynx). Is there any probable reason for that or a workaround? Can I paste any logs here for anybody to figure out what might be going on? When I try XP which is also install, the system won't crash (so far...), so I don't think it's a hardware problem.

I would like to find out how to back up a complete Ubuntu system, and then restore it on a clean harddisk.I have been running dual booting with Win XP until now. I am running Ubuntu 10.04, but have installed quite few add-on. I would like to make an Ubuntu-only machine now, with all the same apps still there, but dont want to go and download everything again. I am looking for a way I can back this entire Ubuntu installation up, and then restore it to a clean drive.
I have an Acer aspire notebook.graded from lucid and now I have a really big problem:every time i disconnect the ac-adapter from the pc, the system freeze completely, became unresponsive to commands and to sysrq. i need to phisically turn off the machine and then back on.
Just curious if it is possible to schedule a complete system shutdown and start up?
My box with ubuntu server on it is only used as an ssh/proxy server, so I would like save on energy costs and add a layer of security by completely shutting it down during the hours I do not use it.
My Ubuntu Karmic running system experiences random lockups. There is no pattern in when it will happen, it can go for days without one, or happen every couple hours. Only thing I can notice is that it happens most often when I run Firefox, but when it happens, it happens regardless of me having Firefox open on a website with lots of Flash content or not. When the lockup happens, I cannot move the mouse - the led light on my mouse shuts off, I can't move the cursor, the whole UI becomes unrensponsive, there is no blinking lights on the keyboard, REISUB does not work, only hitting the reset button on my case helps. After reboot, there are no indications of errors in any of the logs that I can see.I have ran memtest for 24 hours, and it completed without errors.
Additional information:
1. LSPCI output:
Code:

When I try to shut my PC down (press the shutdown button in KDE 4.3.4), the desktop quits, but the console screen does not appear (the CTRL+ALT+F1 screen). Well, technically speaking it appears but only a still (not blinking) cursor is shown, otherwise the whole screen is blank. This means that not only the X freezes but whole system, because the keyboard is unresponsive too. It happend multiple times now, and every time I reboot after such event, some kde rc files (amarokrc, kmailrc, etc...) get deleted due to the automated filesystem check (unclean umount), which means that I have to reconfigure these apps again.
My home partition is on a separate EXT2 partition (this way I have full r/w access from winxp) and every time this is the only one which gets corrupted. The system partition (which is EXT3) is always intact (no fsck starts on boot). I'm using Debian Squeeze by the way.
when my monitor turns off after 30 minutes, I cannot do anything after. We're talking complete lock down of Ubuntu 10.04 64-bit. Not even alt+printscreen+REISUB reboots the machine; I have to do a hard reboot (which sucks and is hard on hardware).
I have been researching the web for a program which will allow me to backup my entire hard drive so that I can restore my system if need be. I am however unsure which is the best one to use if I want to achieve this:Somehow I want to back up my hard drive containing my ubuntu system byte for byte so that if the hard drive were to fail I could simply go to the store, get a new hard drive, restore my backup and be up and running again without having to do any re installments of ubuntu or any other programs for that matter.
What is the easiest program that does this? I would like it to support incremental backup.rsync with the "Back in Time interface"?bacula?
All of these freezes happen either while I'm in Nautilus or I'm opening Nautilus. The usual Ctrl+Alt+Fx (x being one to six) to get into the backstage does not work. If I have some music open then it would start looping the last couple of seconds.Now generally I would go check the logs, but I see no nautilus logs so what should I check?This is all pretty recent. I think that this started to happen when one day exim4 (and some packages all marked exim) got updated but I cannot be certain. Major playing-around after that would be some Wine issues but the system froze once before all that Wine fun.So step one, what should I check?
Happens on Jessie AMD64 with mate, I can't go to a tty to kill mate system monitor, mouse stop working, keyboard stop working. I tried changing the theme, and now it freeze opening mate system monitor.

I am running Fedora 8. Each time I run a YUM command, I get the message that there are unfinished transactions, and to run yum-complete-transaction. Upon running yum-complete-transaction, it fails with this error. How can I remove this uncompleted transaction so I can finish the last one?
I've trouble with booting up xubuntu koala: When switching to the x11-login, the computer freezes during the change of the screen-resolution. Even switching to a console (ctrl+alt+F1/F2/F3...), ctrl+alt+del or pushing the power-button is not possible. After switching off the PC manually, it won't boot at all and freezes directly after switching on again (at bios-time).
Turning the PC off and on again helps - everything is okay afterwards. This doesn't happen always but it is annoying. Sometimes I have to try this procedure 5 o6 times until I can use the computer. Which of the thousand of log-files is the right one to look in? I am using Xubuntu and a Ati Radeon Xpress Graphics card, along with an AMD64 and the 64-Bit-Version of Xubuntu.
Ever since I made the switch to Ubuntu I have had a problem getting back to the X Windows environment from Virtual Terminals. Control+Alt+F1~6 work fine but when I try Control+Alt+F7 my screen freezes.
I have been trying to find a solution to this problem but it doesn't seem to be affecting many other users. Not sure if it matters, but I'm running 64-bit Lucid Lynx.
I'm now on 11.04 (64 bit on a desktop), but had the problem on 10 as well. I get the occasional complete system freeze. There is nothing in the logs indicating a problem and it is not the graphics card, as I cannot ssh in from another machine. It sometimes happens after three days of running and sometimes after 20 hours.
After a hardware freeze, my system boots directly into the Ubuntu screen with 5 dots and hangs. Booting into recovery mode loads the tools menu then freezes before I select anything. The system still boots and runs windows 7 from the same hard disk just fine. I've booted a live cd and run file system check on my ext4 partition and it says it's clean. I can mount the volumes and read the data, just can't get the os to boot.Any suggestions before I backup and reformat?
I've got an odd problem and was wondering if anyone had any insight. I'm on Ubuntu 9.10 on a Gateway E-100M and everything works great except for firefox. My machine will hard freeze about once a day when using firefox. The whole OS -- no mouse movement, no keyboard response, etc.I've switched to Chrome for weeks and I get no issues at all. I switched back to firefox and it hard froze within the first hour or so. I know it's unusual that an individual program would freeze the whole OS rather than just crash, but it seems to be a fairly consistent pattern.
I recently re-installed ubuntu to fix my freezing problem, but with no success. disc has no errors. I cleaned the disc and the cd drive, the cd burner has a problem installing while the dvd drive does fine. The computer is a HP Visualize X-class workstation with dual 1000mhz pentium 3s, 2 gigs ecc ram and a ATI AllinWonder 9700 pro @ 2x agp(wish was higher), on-board sound. So my problems are:
1) It randomly freezes within 24 hours regardless of who is logged in or if effects are on or what the load is. mouse is frozen too, completely unresponsive even ctrl alt f1.
2) My sound is screwy. its supported by alsa but i have to play with the volume to get sound and lots of times there are audio errors, it sounds like its robo-trippin. I have tried the sound guide.
3) Desktop effects only work with the user that logs in first. If I try to activate them when I switch users it searches for drivers then says it cant be enabled. not a priority.
Window xp works okay but the graphics drivers are giving me problems so i decide to do a dual boot.
I think I am going to put in a different video card. maybe its not all there, it got hot once when the fan died, put in a replacement and it worked but i see lines moving down the screen when there are blacks.
After successfully upgrading from 8.04 to 8.1 (where even my wireless worked for the first time) I got a system freeze when I tried to upgrade to 9.04.
I suspect the graphics driver but don't know how to upgrade without X running. After booting in generic mode (kernel 2.6.28-1 I can log in the shell but am lost without the GUI.
Don't know if this is a coincidence, but the other day we had a power cut and my laptop went off. When I tried to reboot it got to the ubuntu start up screen, but when it tries to get to the "desk top" screen it all goes blue and black flashes. I have XP and Vista on the same machine and these both start up ok
I had Ubuntu 9.10 .. upgraded to 10.04 LTS... i dunno if its the ati driver or what but when im on wine the games runs fine for a couple of minutes.. 5 to 10 maybe and then the whole system freezes.. cant close cant do anything... the mouse moves though .. and the sound keeps looping, thats if i use OGG on wine insted of ALSA... This looks like it should be on the wine segment but i dont think so... I mentioned wine cuz ATM wine is all i got on this pc as for games.... im downloading urban terror to see if it freezes too...
I remember that right after i finished installing ubuntu 9.10 i upgraded it right away to 10.04 without having the ati drivers installed, after the installation finished... the boot up logo from ubuntu with purple background was at its normal size as usual... But once i installed the drivers.. the ubuntu boot up logo or whatever its called went all BIG like if it was using another resolution, though once it finishes loading, the resolution goes back to normal when in login screen and desktop.
HOw do i remove the drivers completely? do i have to restart after removing them so i can install new drivers? should i use propietary drivers from amd site or the one found by system--- hardware drivers??? why cant i find envy at synaptics?
Im running desktop dual boot system with two hard drives, one with Windows XP and the other with Ubuntu. Ive had no problems with this until now when I upgraded from Hardy to Lucid. Now I have problems with the system freezing on boot up.
Sometimes it will boot just fine, and at other times it will freeze before the login screen appears. When it does freeze, there are flashing lights on the keyboard and the floppy disk light (yes, its an old computer) is lit constantly. The only thing I can do is switch the computer off and hope it will boot up properly the next time.
When I did the upgrade there were a couple of files where the program asked if I wanted to keep the custom file or overwrite it with the maintainers file and I chose to keep the custom one. I THINK one of them might have been GRUB, but Im not sure.
Has anyone had a similar experience and were you able to cure it? I have seen a thread where people have had the system freeze on them, but Im not sure its QUITE the same thing.
Ive also done a clean install with Lucid on my laptop and have had no problems. The laptop is only running Ubuntu.
Im also wondering if reinstalling Grub on my desktop would solve the problem.
a. If so, would it still show both operating systems?
