Ubuntu :: Memory Maxed Out And System Freezes Up?
Mar 7, 2011
Is there something similar to the windows TSR thing in Linux? (terminate & stay resident)
The reason I ask is that after replacing my HD and reinstalling Maverick I've noticed the PC freezing up afew times. It seems that memory gets used up and then doesnt free up after the application is closed. The last couple of times this happened today I was doing
1. Copying a number of photos from my flash drive to the HD
2. Burnt a disk with Brasero.
After doing this it froze and I had to crash the system and reboot. I don't remeber this happening before.
Apart from this memory problem it's working OK I think. My system specs are below
Code:
mbdb@M2000:~$ sudo lshw
m2000

I am trying to run a simple perl program that requires getting stock price data from yahoo for just 1 ticker symbol, and it was running fine till this morning, wherein it froze and displayed the message: Out of memory!
I cleared my cache by running the following:
Code:
$sync
$sudo echo 1 |sudo tee /proc/sys/vm/drop_caches
$sudo echo 2 |sudo tee /proc/sys/vm/drop_caches
$sudo echo 3 |sudo tee /proc/sys/vm/drop_caches
but it hasn't helped.
Even Firefox has been freezing, so I basically cannot do anything on my computer.

So now I've got my iMac G3 running nicely I was wondering how I go about running a burn in test so that I can see if I can improve the cooling in places by manipulating airflow, I have a thermal cam but I want the machine running maxed out in order to see where things can be improved.CPUBurn in the repos isn't coded for PPC, only x86 x86_64.

I have an HP dx5150 with Ubuntu 11.04. I recently added 2 new memory chips (total 4) with the same specifications as the originals. The memory is recognized by the BIOS and Memtest returns no errors. The computer boots normally and functions normally for an hour or so, and then freezes. When it freezes it does not accept any input and the screen gets displays a bunch of small green or purple lines. Here is the output from lshw:

Using 10.04 Netbook version. I am finding on my Asus EEE 901 that sometimes file copy just seems to freeze - seems to happen usually when copying from the built-in SSD memory to the plug-in SDHC memory card. I have tried reformatting the card and using a different card. It is not just this computer since I found the same thing on my last Asus which was the 900 model.
I am told that there are issues with Nautilus. Is there anything which can be done to improve this or is there anything else which I can install besides Nautilus? I am assuming that there is some issue related to Ubuntu's handling of SDHC memory cards.
It is becoming annoying because it seems to work sometimes and then not. When it happens only option seems to be to turn the netbook off and on again. Even if the file copy is cancelled the card seems to be unaccesible until rebooted.
Also after a certain point it seems that when I try and copy new files to the card, they appear to copy ok but obviously are corrupt in some way - when you try to play videos for instance they are faulty.

Is there a system admin tool for RHEL on montioring and logging system memory used and released that can dump to a log file?I'm having an issue with memory not being released when an application is closed. I need to have a tool monitor and log so I can troubleshoot to verify that it's an application not the OS.

I have Mythbuntu 10.04 installed on an exclusive HTPC and working great... until tonight. After letting the system update some packages (161 packages if I remember right), I suddenly have an issue where the graphical system won't start. After researching I found three error messages that might be causing that.
1. At the start of splash screen I see "UUID=xxxxxxxCD7 not ready yet or not present" I checked in /etc/fstab and found that this is the swap partition. I don't remember seeing this before so this could be the culprit.
2. I'm not at the computer in question right now but I saw a Plymouth error about "mountall" and then the message "plymouth command failed". Not sure if this could be the main error.
3. after a while (usually ca. 1-2 min) I receive thousands of errors of the kind "out of memory"... "kill process XXXX" (process vary wildly e.g. dbus-daemon, mysql, etc)... "process killed"..."respawning"
After error 3, I'm not able to switch to graphical console (ctrl-alt-F7). If I was in the graphical console at this moment, I simply can't switch to the CLI console. I'm always afraid of updating my system since I've seen lots of things breaking afterwards (usually the proprietary graphic drivers) but this is really strange.

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?

in this example, my memory 993.4 MiB memory is said to have 575.9 MiB of it used and 163.4MiB of my 2.8 GiB swap memory used. but in my processes tab, the most memory hogging program is 98.3 MiB, and Pidgin, 25.9 MiB, and 18.9 MiB, 14.9, 6.2,6.1,5.2,3.4,3.3,1.8,1.8,1.7, etc. I'm certain these don't add up to 575.9 MiB so where is all this extra memory usage coming from?
also, why is data measured in MiB?

I have a problem with recognising my mobile phone's memory card in Ubuntu 9.10. When I plug the phone in it starts the mass storage mode, but nothing happens in the PC. I suspect that I may have deleted phone's icon from the desktop, and I don't know how to bring it back. Also the memory card doesn't appear anywhere: nor in the Places tab, nor in Media folder.The phone is Samsung U900 Soul.

Rhythmbox stalls my computer. I start it and within 10-20 seconds it starts to search something (i.e. in the right bottom there appears a box with a red box sliding left and right). It consumes all my memory (1 giga) and the only thing it does is identify text files in a general directory, NOT in Music. I have completely removed the install, installed it again, the same text files earlier IDed are still there? Is there an alternative?
Computer details: Intel dual core, Nvidia, 64 bit Lucid. The flaw is that it runs on single memory.

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?
b. How do you do it?

When I click certain links, such as the one below, Firefox consistently crashes.
The bigger problem is that when it does, everything grinds to a halt, and I have to press the machine's power button.
Is there a way to kill processes when the system locks up? This is on Ubuntu 10.04 Lucid Lynx, using GNOME.

I am using Ubuntu Lucid and have a problem with firefox (V 3.6.10). It often causes the whole system to freeze nearly every time I access skypoker.com, sometimes straight away, and sometimes within a few seconds or a few minutes. The whole system becomes unresponsive, with only the mouse being able to move (not click). I haven't seen this problem occur with any other sites. This problem does not seem to occur when I use google chrome, but it does with Konqueror. Control + Alt + F1 is unresponsive, along with every other keyboard stroke or mouse click and the only way I can do anything is to restart the computer with the power button.

I am running Ubuntu 10.10 on a Lenovo Thinkpad T61p with 2GB RAM. When I was on Ubuntu 10.04, one day suddenly Azureus hung at the 'loading plugin' screen as it begins. I had to hard reboot my system and it(Azureus) never worked after that so I removed it. Then after a couple of months same thing happened with Adobe Acrobat reader. As soon as I opened any pdf and started to scroll, it hung. System didn't respond and had to hard reboot. I moved to foxit reader Then I upgraded to 10.10 and now mplayer hangs occasionally if I try to switch it to full screen. System stops responding totallyn Where to begin debugging from ? I can't figure out any pattern or any way to reproduce it. I haven't tried Acrobat reader and Azureus on 10.10

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 running Ubuntu 9.04 side-by-side with Windows XP.
Today, all of a sudden my system kept freezing up, forcing me to manually power-down my computer. Well, I tried picking an earlier kernel to boot from and, sure enough, there was no longer a problem.

I just installed Fedora 13 onto a "new" (to me) box, and everything seems mostly fine, except that I only seem to be able to use about 900.2 MiB of 991.4 MiB of RAM memory, according to System Monitor. I haven't set up a swap partition yet, so the problem became very, very, very obvious. When I get to about 890 MiB usage, everything goes very quickly downhill, locking up, etc. The peak I saw was 900.2 MiB. What's going on? Does this have anything to do with the system being 64-bit? Might the memory be bad?
