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.

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 am getting a strange font problem (see attached screenshot) for a user logging in over VNC Server, I am also logged in over VNC however I am no experiancing any problems... This was the case on CentOS 5.3 and on 5.4. I have tried removing the .vnc dir in the users home dir and re running vncserver so that it recreates it, I found this in the logs:
1. (nautilus:14718): Pango-WARNING **: No builtin or dynamically
2.loaded modules were found. Pango will not work correctly.
3.This probably means there was an error in the creation of:
4.'/etc/pango/pango.modules'
5. You should create this file by running pango-querymodules.

I am installing openSUSE 11.2 on a laptop. After installation, reboot, auto-configuration, the screen show lines of text following "Starting SuSEconfig. The latest line is "Creating cache files for fontconfig". I don't understand why this specific operation takes too long; since almost an hour has passed. Is there a way to speed up and complete the process so that I can login and start using openSUSE? I did try hitting the spacebar and moving the mouse but nothing happens.

View 3 Replies View Relatedi noticed few times that my ram usage in gnome increases high. So i found that python is using more than 500 MB Ram. Normally i didn�t notice this python. What does it do?
I am not sure, but i think that these increasing has something to do with skype/empathy (i think it grows after using this programs...
So, i killed the process and ram usage is normal.
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)
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.
View 2 Replies View RelatedI 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.
I'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 calling the insertNode() function with seq = 'MISSISSPPI$' and alphabets = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ$'

Weird behaviour I should mention is that when I check for NULL pointer in node->child[index], the unassigned values are not null anymore, they point to arbitary memory.
we found that if we use 'top' to show the memory usage of a server (SuSe Linux 10), we can get virtual memory usage as well as 'Resident memory' usage. For virtual mem or a particular process, it is around 1.1GB, which is large but for resident memory, it only consumes 300MB. Are there anyone who knows what the differences are? I would also like to know whether the difference (1.1GB - 300MB) = 800MB are actually available for use by other applications in the system.

View 2 Replies View RelatedI am monitoring physical memory in a server I administer, and my hardware provider told me they had increased physical memory size to 4Gb... However, using several tools (free -m; top; dmesg | grep Memory; grep MemTotal /proc/meminfo I discovered that I actually have 3Gb, not 4... But, my doubt comes from the fact that dmesg | grem Memory tells me I have 3103396k/4194304k available The first number is effectively 3Gb, but the second one, is 4! so, why I am looking at this two different numbers?
View 1 Replies View RelatedI am writing an application that wants to access periphals registers outside the standard (allowed) memory area.
Doing so gets me "segmentation fault".
I know, this is natural behaviour.
One way of getting around this is writing the module which has to be loaded by linux. I will consider this some time later.
For now, I want to come to some quick result and allow linux or gcc compiler to write to those memory areas of periphals. Is there a direct way to do so?
Is that possible that SHM shared memory is counted as cache memory on Linux with kernel 2.6.18?If find it really odd since this memory is not file backed, but I have a piece of code that loads data using shm_open+mmap, and it generates an amount of cache memory in /proc/meminfo that corresponds exactly to the amount of shared memory (I load that data from a file but I am using posix_fadvise(fd,0,0,POSIX_FADV_DONTNEED) to ensure this file is not cached and I made sure that it is working as expected). As far as I know SHM memory was not tagged as cache memory with kernel 2.6.9.If it is the case it is really unfortunate since normally cache memory can be considered to be part of the "available" memory since it can be flushed promptly but this is clearly not the case with SHM memory... Is there an easy way to get the total amount of used SHM memory on a system?
View 4 Replies View RelatedThis is my first post in these forums. I'm still quite new to Linux (using Mint 9) so please bear with my not-very-articulate question(s)When I boot up and open up a tty terminal I get a message saying "Memory corruption detected in low memory." I've done an extensive google search about the issue and it seems not uncommon. I ran a memtest with no errors returned, so I'm sure that there's nothing really wrong with the memory; apparently it's a bug in the kernel that's causing this.
