Ubuntu :: Disk Thrashing/apps Freezing For Approx 30 Seconds

Sep 8, 2010

I've been having this issue since at least 9.10. I'm randomly encountering disk thrashing and application freezing which lasts around 30 seconds. Some applications seem to encounter this more often than others. Firefox and Picasa are pretty reliable at reproducing the issue. It also happens often when I'm using Transmission. CPU usage is not unusually high during the 'thrashing' sessions. Running iotop hasn't shed any light on the problem either. I was wondering if anyone else has encountered this or maybe someone could give me some clues. I'm running a dell inspiron 530 with ubuntu 10.04 64bit. I have 4gb of ram. Here is my 'df -h' if that is helpful.

Filesystem Size Used Avail Use% Mounted on

OpenSUSE Multimedia :: VLC - During Video-playback The Screenbrightness Is Turned To Zero After Approx- 30 Seconds

Dec 1, 2009

I've got a problem with my VLC MediaPlayer (v1.0.3-GoldenEye). During video-playback, my screenbrightness is turned to zero after approx- 30 seconds of playback. After turning the screen brightness to high again, the same thing starts over again. By now, I encountered that changing screen resolutions (e.g. after closing a fullscreen application with a different resolution) also turns my brightness to 0.

Ubuntu :: Flash Plugin Causes Disk Thrashing?

Mar 28, 2011

Recently I have found myself getting terrible disk thrashing, to the point that my desktop is almost uncontrollable. I have found that killing the plug-in container task (I'm using 64-bit Firefox 4) brings the thrashing to an end. In other words it's a problem to do with Flash.

OpenSUSE :: Hard Disk Thrashing, Esp After Boot?

Apr 24, 2011

Acer Travelmate laptop, 1.3GHz Pentium M, 12MB Ram.pensuse 11.4 (upgraded from 11.3)Vanilla install, not running anything special, always startup and shutdown from scratch, never sleepFor several minutes after KDE appears and I open an app (any app, e.g. Chrome) the hard disk is going nuts. WTF is it doing and how do I stop it? Also some programs take years to start, e.g. digicam took TEN minutes the other day even after waiting a while after booting, the disk thrashing the whole time. But in 11.3 it started almost instantly.

Debian Installation :: Hard Disk Thrashing With Squeeze?

Apr 22, 2010

Just loaded Squeeze (KDE) onto a partition on my desktop and am a bit alarmed by the disk thrashing thats going on? Damn light on constantly. if I didn't know better I'd think I was using Vista. Is this something to do with 'nepomukservices' that seems to be taking a fair amount of cpu time? Not used to KDE 4 so maybe this is normal.

OpenSUSE :: Tracker Store Burning CPU And Thrashing Disk?

Sep 24, 2010

I've noticed tracker-store burning CPU and thrashing disk when I login to a KDE session. I'm tempted to disable it by modifying /etc/xdg/autostart/tracker-store.desktop. But before I do that, what added value does it bring to the party? It seems like it's mainly involved with desktop indexing, which I never use (does anyone?).

OpenSUSE Install :: 11.2 Keeps Freezing - Getting Black Screen And After 30 Seconds The DVD Player Stops Running

Jan 17, 2010

I am trying to install 11.2 but it keeps freezing. I press install and the Linux kernal loads and afterwards I get a black screen and after 30 seconds the DVD player stops running. I have also tried to the online network install and the exact same thing happens. I also tried a DVD I have of 11.1 which I know is good since I have successfully installed it on other machines and the result is also the same. My computer currently has a dual boot of XP and Kubuntu 9.10.

I am returning to Suse after experimenting with Kubuntu but thought I would leave the Kubuntu on the machine (prefer Suse but Kubuntu installed very easily on my computer). Could the Kubuntu be causing this problem or is the difficulty something else? I have also tried the safe install and the other options to no success.

Ubuntu Multimedia :: Rhythmbox: Accessing Disk Every Few Seconds While Playing?

May 18, 2010

I'm running Lucid and have an annoying problem with Rhythmbox: while playing, it constantly accesses the disk, every 2-3 seconds drrrrd drrrrd. Listening to some silent music is horrible - the output of the speakers is lower than the noise of the local disk.

Maybe relevant settings in Edit->Preferences:
Playback -> Network Buffer Size: 1024 kB
Music -> Watch my library for new files: off

Is there anything else one can change? It can't be that difficult to read a <10MB file into memory right from the start and not touch the disk drrrrd every few seconds?! P.S. I verified by turning off the speakers and start/stop playback - the noise there on playback and not if turned off. Reliably.

Ubuntu :: Running Apps From Across Two Distros On Same Disk

Feb 21, 2011

I really do not know how to phrase this question properly. I am quite unaware of the PC jargon. But I have Ubuntu as the main OS and Mandriva is the second OS on the same hard disk. The boot loader is the Ubuntu. When I want to switch to Mandriva, on boot up I press Shift and then select the kernel.However, if I am on Ubuntu and want to run an application which resides on Mandriva, how do I do that? My fstab file does not even mention Mandriva. However, the file system does show up that file and I can open any files I need by clicking on GUI "Places". But when I try to run any of its applications by clicking the appropriate file on its /bin file nothing happens. A pop-up window briefly flashes and disappears. So my questions are:

1. First how can I change directory so that I am on Mandriva. Can' cd ...something' take me to that file because I see it in "Places" as a 36Gb file system?
2. How can I run an application which resides on that file system e.g., R or Octave which I do not have installed on Ubuntu, without rebooting into Mandriva.
3. Can I do this from command line.
4. And finally, can I do the same from Mandriva i.e., access Ubuntu from it.

I did read quite a bit about mounting files and fstab, but the fstab does not show the file system I am talking about. These are the outputs from Ubuntu os.

General :: Fullscreen GLUT App Display Blanks After Approx 30 Minutes

Apr 6, 2010

I'm running a fullscreen display app which shows a 3D scene in OpenGL. The app runs continiously throughout the day unattended.

Here's the sequence of events in how it's loaded:

1) The computer is turned on, and boots into F11 (x86_64)

2) A non-privileged user is automatically logged on

3) The gnome startup applications list contains an entry for a loading script

4) The loading script waits for the network interface (eth0) to ccome up, then starts the display program

This all works just fine, except that about 30 minutes after the computer is turned on and the app starts running, the screen blanks out. Attaching a mouse to the system and moving it around a bit brings the screen back to life. Likewise, SSHing into the machine and killing / restarting the application works as well. Once either of these fixes has been performed, it runs flawlessly for the rest of the day.

I have turned off the screen saver, and set the power settings for monitor shutdown to 'never'.

General :: Postfix And Gmail / Dropping Approx 50% Of Mails With An Error?

Nov 14, 2010

I've setup postfox on Fedora 13 in order to send emails to and from gmail. I thought this was working, but it is dropping approx 50% of mails with an error. The other 50% work OK. It seems completely random.
I've read the link but I stil dont quite understand.

My machine is just a PC, on talktalk's network in the UK.
I use dyndns to allocate a DNS alias (well several actually) to my dynamic IP address - not sure if this is relevent.

Is it failing due to a reverse DNS lookup on the dyndns host? Or is it because it cannot resolve my localhost.localdomain?

I used to have this running on opensuse and swear it used to work 100% of the time.
What am I doing wrong?

Ubuntu :: 10.10 - What Process Start Thrashing HD

Nov 20, 2010

ubuntu 10.10 At times something starts thrashing the HD. Often after the computer has been taken out of Suspension. The whole things slows down and stays slow. This can be fixed by logging off (which takes quite a while under this condition while the HD light stays on, solid) and logging back on. Then the system becomes responsive, with only HD light flickers. Anyway, I can't determine what process is doing the thrashing. System Monitor doesn't show any memory problems, and neither do top or htop. htop shows plenty of swap space available, and memory usage is on par with what it looks like when there is no thrashing. Is there some tool that can display what processes are running the HD so hard?

Networking :: UDP Thrashing 224.0.0.54 (140 Times Every Second)

Jan 12, 2010

My ADSL router NAT's any computer behind it here at home. I have a PC or two a Sun ultra10 and ultra5 and E450 etc.

The problem is my PC reports via "tcpdump -i eth0" that
22:54:47.035683 IP icute.pelnet.net.50683 > 224.0.0.56.46144: UDP, length 1292
is going on 140 times every second.

How do I prevent this from continuing and why is it happening? If possible I don't want to invoke iptables as my NAT router does a fine firewall job.

General :: Hard Drive Thrashing With EXT4

Nov 1, 2010

I'm dual booting Ubuntu 9.04 and 10.04 on an ASUS P5VD2-MX SE mobo with 3 hard drives, a couple of DVD writers and a multi memory card reader (USB).

The hard drives are:-
1 250Gb SATA MAXTOR STM325082
1 80Gb PATA HITACHI IC35L090AVV207-0
1 80Gb PATA MAXTOR 6Y080P0

9.04 lives on 2 ext3 partitions of the 250G SATA
10.04 on the 2 ext4 partitions of the 80G MAXTOR
The HITATCHI has 1 ext4 partition mounted as a common data area for each O/S
The 250G drive has GRUB Legacy in the MBR with its files in a small ext3 primary partition chainloading the 2 O/S's, GRUB Legacy for 9.04 and GRUB2 for 10.04. It also contains the common SWAP partition (primary)

When I boot into 9.04 everything works as expected with as far as I can see no unusual disk activity even when the ext4 data partition and the 2 10.04 ext4 partitions are mounted. When 10.04 is booted however, after about 5 minutes (irrespective of whether or not the other partitions are mounted) I see the hard drive activity light come on and stay permanently on. The system monitor shows nothing unusual. dstat doesn't give any clues either. I've tried running iotop but it fails with a missing CONFIG_TASK_DELAY_ACCT error.

Is this a known problem with ext4, should I rebuild 10.04 onto ext3 partitions? Are there some special ext4 mount parameters I should use? (I simply copied the fstab lines from 9.04 and just changed ext3 to ext4). I've read that the journaling process(es?) for ext4 by default commonly access the drive(s) every 2-3 secs but that should just cause a flicker surely.

Fedora :: Rhythmbox Thrashing Hard Drive On Startup

Apr 29, 2011

I'm using the rhythmbox installation that ships with fedora for my music playback. Every time is start the darn thing up though I can hear my external disk (media library) being accessed really hard. I assume this is part of some sort of library self check and probably a check for new music(?). So this got me wondering on how rhythmbox keeps up with my media library and if there is a way to make it more! I assume that atm rhythmbox just checks every file it now in my library for 'something' and at that also checks for new files and folders in the library directory. So I guess It would be quite a boost in startup performance (disk thrashing) to just skip the existing files checks. Right? Well, I obviously don't know how rhythmbox ticks so be nice.

Ubuntu Servers :: Crashed - None Of The Sites Were Responding - Sounded Like It Was Thrashing The Hard Drive

Aug 2, 2011

I have a ubuntu 11.04 LAMP server at home.

Its runnign a few small sites on a drupal CMS.

This morning I found none of the sites were responding. The server itself sounded like it was thrashing the hard drive.

It wasnt responding to the FTP client or SSH connections. Web pages just sat there like they were loading very slowly but never actually loaded.

How can I find out what went wrong. I dont have a massive amount of experience with linux, particularly the server variant.

Its worried me a little that the drupal report shows several page not found errors like someone (a bot maybe) was trying to see what php setup files they could access.

Ubuntu Servers :: Give Power Users Ability To Access All Of Their Folders Without Thrashing Security.

Feb 8, 2011

So, I am looking to implement an FTP server with Isolated Client accounts/directories where a client can only access what's in their directory. I also need to provide my internal user's (content managers) the ability to upload, delete, etc from all of the Client accounts. The simple part is creating the secure client accounts. It's a matter of changing DIR_MODE in adduser.conf to 700 or 770, creating a user, having the FTP server chroot them to their home directory, revoke/restrict shell/ssh access and maybe even slap on some ACL to prevent botched permissions.The hard part is figuring out how to give my power users the ability to access all of their folders without thrashing security.

My first thought was to put all of the client user-groups in a parent group and having my internal users inherit group permissions..but you can't have groups inside of groups.My second thought was to put all of the client users in the same group and prey that the FTP chroot is enough to keep them from poking around but then I have the problem of how do my internal users access other user directories if they are chrooted. Do I create a second server without chroot.do I create some weird nested homedir structure..I honestly have no idea how to satisfy both requirements (secure client accounts and privileged user accounts). I need my privileged users to authenticate against Active Directory via Likewise open, LDAP, etc and I don't care how the clients authenticate. Though, I would prefer to have both file and FTP-server level protection just to make sure no one can see the other client's data.

Ubuntu :: 64-bit Freezing - How To Fix It

Dec 13, 2010

Once or twice a day, the entire system just locks up, and the only way I know to undo it is with a hard reset. (The mouse cursor still moves around--but it can't click on anything.) It did this with a clean Lucid install, and still does it with Maverick. Often, it's when I'm in Firefox (and usually a site with Flash), but I'm not 100% sure of that.

Now, one issue is that I don't know how to diagnose this issue. With the system frozen, it's hard to probe anything to see what went wrong. Is there a particular log file somewhere that I should check out, that may say what happened?
