I'm trying to stop swapping on my system (without using swapoff -a). So I do: echo 0 > /proc/sys/vm/swappiness vmstat 5 and I still see swapping activity under si and so. Am I missing something?
View 2 RepliesWe have a four socket amd machine, running barcelona processors, with 64gb ram.The system runs for extended periods just fine when the system is running up to or below the 64gb memory limit. A typical load on the machine has short periods where the machine uses heavy amounts of swap space (30+ Gb). We have a swap partition of around 96Gb. When we push the machine into heavy swapping, the machine will fail within 24hrs. Has anyone experienced this problem and is there a solution other than buying more physical memory? Or am I wrong and maybe the physical memory is the issue? I thought maybe it was the memory itself, and after stripping the memory down, I get the same problem...failure upon heavy swapping
View 7 Replies View RelatedNot quite sure where to post this, so please bear with me ... I have a server running in a datacentre. Its running apache and every now and then apache fills up the memory, and the disk starts to swap out. There must be some kind of php / apache memory leak, which I can't locate, but anyway, in the meantime, I wrote a script which alleviates the problem - this is the short version:
Code:
#!/bin/bash

I have this situation: I installed F13 on my laptop having an Intel Graphics Media Accelerator. The screen of my laptop was flickering and i did a 'yum update'. The flickering didn't stop, but after suspending the system once, the flickering stops and everything is fine. Now after each reboot i have to suspend the system once for the flickering to stop. Please help.
After discussing in #fedora in freenode, some people asked for these (i'm posting in case you need them too):
$ lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12)
/var/log/Xorg.0.log -> url.
I installed F14 and I have been having some issues with the usage of the ram memory. Here is the situation: while working with firefox, amsn, and VLC, suddenly the system stop responding, I just can manage to check system monitor and the ram is at 89% (of 1GB) and the swap at 50% (of 1.4GB). I can do nothing then I just switch off the machine. After that using the same applications everything is fine. I was using F12.

I had to go to bed so I changed the sleep timer on the laptop to 2 hours, the time it would have taken the upgrade to complete. I woke up and the laptop was off, now only the grub menu shows up and the laptop won't boot. I tried doing this: - When the machine boots up, press Esc to get to the Grub menu - Select one of the recovery mode options. This will boot you up to a single-user root prompt. - Run sudo fdisk /dev/sda (this assumes that your hard drive is at sda) - Type p to see which hard drive partition is labeled Linux swap. In my case the partition was /dev/sda5. Type q to exist fdisk. - Type these commands:

I have a HP Laptop with Ubuntu Hardy installed. The system beep makes rapid clicking sound at login window that slowly dissipate and clicking that, so far I can only fix by rebooting, when I play music, reboot after hibernating, and when waking up from suspend. I've turned the system beep off in System/Preferences/Sound but it doesn't do anything.

View 4 Replies View RelatedWell it turns out my system has logged out more then once on its own. I had the system updated and upgraded from 7-3-11 and it did this about once a week. On 7-18-11 I did a full update and upgrade and it logged out a few times in a couple of hours. It does it while I am away and the system is in screen saver mode. I used my partition clone and restored the system back to 7-3-11. Has any one else ever had such an issue?
View 2 Replies View RelatedI'm running Ubuntu 10.10, 64-bit on an HP 8740w. Sometimes (I don't have the frequency yet, but it has happened a half-dozen times in the past couple of weeks) when I insert a USB storage device the system hangs, requiring a power-cycle. I have been careful to either eject or "safely remove" every USB device, but it still happens. I believe it only happens when I remove a device and later re-insert it, but I don't have enough data points to be sure.
Most of the time, I'm running VirtualBox, but I haven't captured the USB device in a VM.
First question - how can I go about figuring out what might be going wrong? Once it happens, my options are extremely limited (power switch). When this happened one time I left the system for 30+ minutes, and it did not recover.
Of course, when I wanted to see it, I did 10 insertions/removals without a hang.
We use Ubuntu 10.10 (32 bit) as a backup server.
The machine is quite ild but still working well.
All works very good but every few days it is crashed and freez.
I do not know what real happeny since i do not work on it, but tring to ping it fail and the monitor is blank.
What can I do?
Which log is relevant?

View 1 Replies View Relatedsince a few days (maybe one week and after an automatic upgrade), I could see a strange behavior of gnome-system-monitor. After a boot, everything is normal. But if I log-out, and then log-in again, the problem begins. Impossible to close the gnome-system-monitor window (by clicking on the window upper-right close button). I have to terminate the process. And this process takes about 50% of CPU. In the same time, a dbus-deamon process takes the other 50%. When I terminate gnome-system-monitor process, the CPU use drops down to 6%.
View 5 Replies View RelatedActually I'm not sure that it's swapping like mad: I've done more testing and it looks like there may some interference causing the noise that may be correlating with network usage. I'm accessing a MacMini (with MacOS X 10.4) from my Linux machine using VNC. My Linux machine has 4 GB of ram and I run a lot of various apps on it and I've got no issue at all. It's all snappy and don't hear the hard disk swapping/read/writing too often. Now with VNC, the hard disk is swapping like mad. When I'm moving things on the OS X desktop. So I was thinking of creating a ramdisk and forcing the temp VNC files to go into that ramdisk but the problem is I can't find any temp files.
I've attempted to do that:
#!/bin/bash
while [ true ]
do
lsof | grep vnc
done
The VNC version I'm using is this one:
$ vncviewer -version

No matter how much data is coming from the Mac, there should be plenty of memory (4 GB of ram) so there's really no reason to swap like crazy.
I currently have Ubuntu installed onto my laptop, on a single drive partitioned into /root /home /swap. I now have an additional spare HD that I was thinking of installing Win XP onto. So If I needed to use XP for a specific program then I could just swap out the HDs instead of having a Dual Boot system on one drive. confirm that by swapping out the HDs this will not affect the Grub Boot Loader and I will be safe to do this without screwing up my Ubuntu, as if it will screw it up I will just stick with Ubuntu on my Laptop and forget about XP.
View 2 Replies View RelatedThe hdd that my system boots from is named "sdb". But sometimes it's named "sdc". It changes from boot to boot. There are four hdds in this desktop and my boot disk keeps swapping names with a data disk (sdb and sdc). No raid. Never affects the other two disks. I am running Ubuntu 10.10, but this problem began when I was a running 10.04.
View 5 Replies View RelatedI have installed xubuntu. I have a total of 12034MB of main Memory of which ~1000MB are normally used.When I leave the computer and come back, it is swapping a lot. Whenver I display a window (firefox i.E.) that I have not displayed yet since I left the computer alone, I can here the HD working, and the system monitor shows me how more memory is used and less swap space.
But there is absolutely no need for it. I have at least 10000MB of free Memory at all the time!Can I somehow tell my xubuntu installation to stop swapping unless there is really little main memory left (lets say less than 2000MB)?My kernel version is 2.6.35-29-generic because I have trouble with the raw1394 module in the newest version.
I am using Ubuntu 10.04, 64 bits. I need to swap sata hard drives (they are installed in drawers). If I umount and remove a disk, and then put the same drive in it's place, I can mount it again with no problems. If I put another disk in place of the original, it says: mount: special device /dev/sdc1 does not exist. If I reboot, the new disk is mounted correctly (sdc1 is in fstab).

View 1 Replies View RelatedI am using ubuntu 9.10, but I also noticed this with 9.04 on a different laptop. Sometimes when I am using skype, for no reason and after no particular event the audio for everything in the system except for the skype video will just quit, and sometimes the sound doesn't even work for the video either. Buttons don't make their sounds any more and I can't play music or hear audio on flash videos. By can't play music, its weird because the music player (amarok) will just scroll through my entire playlist really fast like it can't play any of the songs.
To solve the problem, I have to shut down skype and firefox, but I'm not sure whether I can just shut one of them down without having to shut down the other. My audio settings in skype are all set to pulse and it is adjusting the mixer levels automatically. This problem has persisted across two laptops and two versions of ubuntu (9.04 32 bit and 9.10 64 bit), so I think it's about time I finally asked how to fix it.
Every time when I right click the USB drive icon and select "Safely remove drive" I always get this error message
FAILED: No such file or directory
even though the icon does disappear from the desk top. I have been ignoring it since the USB drive seems working fine.Now I have a more serious problem. When I tried to copy files onto the USB drive it says "read only file system" and doesn't let me. I tried unplug and plug the USB key but that doesn't help.
