Server :: Stop Someone Eating All The Memory?
Apr 17, 2011If I have a centos linux server, how can I stop a user on the server from eating all the memory and swap space memory, maybe due to a poorly written script, infinite loop etc?

Server :: Can't Figure Out Which Processes Are Eating Memory
Nov 6, 2010I'm running several SHOUTcast server instances and a WowzaMediaServer instance on a CentOS machine. I'm experiencing a memory leak problem, but I can't figure out which processes are eating memory.
TOP command reports as follows:
[Code]...
Something misterious to me (I'm still a Linux newbie) is that TOP reports a total of 7.5GB used ram but very small percentage for single process (0-1%). Memory consumption starts at 1GB/8GB after reboot and in three days running gradually increases up to 8GB. I'm practising with Linux, but I still miss a lot to understand what's happening on my system. For instance, are there linux kernel logs saved somewhere that I can look at?
Ubuntu :: Memory Leak / Some Process Eating All Memory
Jan 29, 2011I have had a fresh install of Ubuntu 9.10 and installed some software after that.Since third some, some process is eating half of my memory.I have checked processes running in system manager but everything is normal.Maximum is consumed by compiz which is about 26 mb, seems very normal.I did restarted my computer several times, and in the start for 5 mins, its fine after that again my cpu fans runs at very fast speed and my one cpu is used up 95 % (I have dual core).Please help me out, this invisible thing is driving me crazy.I am attaching my htop screen shot (sorted by cpu %), now the cpu is not used by completely but fan is still struggling hard and fast.

Nov 21, 2010I have installed Debian Lenny today from netinst cd. It all went good, hen I installed some basic utilities, daemons and libraries like dbus, hal, libgtk2.0, libasound2, alsa-utils, htop (for checking system load). Then I installed X.org with commandaptitude install -R xserver-xorg xserver-xorg-input-mouse xserver-xorg-input-kbd xserver-xorg-video-intel xinit xterm twmI used -R to pull less dependencies. When I ran startx X Server started, and I got on twm. But when I checked on htop, my memory usage was 175MB, and before starting X Server it was only 25MB. Why is X Server using so much memory on Lenny? I also have Debian Sqeeze on a different partition, it uses so much memory with all gnome services running+ iceweasel and amsn.

Ubuntu :: Xorg Eating A Lot Of Memory / Makes System Freeze
Apr 7, 2011Xorg takes 700+ mbs of ram, then in matter of hours it fills the swap and then system basically stops responding or whatever. And because its constantly allocating, it degrades perforamce horribly.Interesting thing is I never had this problem before, recently one of my ram modules broke (2+2 GB) and now I have only one, but it still doesnt explain the memory overuse. Windows 7 works perfectly fine.

General :: Testing - Stop OS From Allocating More Memory To A Process
Dec 2, 2010I want to test that a process properly kills itself and restarts when it can't allocate needed memory. One idea I had was to start other memory-consuming processes and hope that OOM killer kills the process being tested, but 1) this isn't quite the same; 2) it may kill other processes instead; 3) since this is an embedded system, I don't have any programs available except for the system under test and BusyBox.Is there a more direct way to ensure that Linux won't allocate memory to a process?

Feb 3, 2010we 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.

Using yum I installed vsftpd and ran into problems, thinking it was something I might of done I did a fresh install of CentOS and I still recieve the same problem on a fresh install so it is nothing I have done to the server.
The problem is when connecting via a sftp client I get an out of memory error. This error is listed in the putty faq ( url ) under A.7.5, there is a brief explaintion of the cure under A.7.6.
there is mention of a login script but I don't know where this is located. I'm a novice at Linux but by no means incompotent when it comes to computing.

Fedora X86/64bit :: F11 - Plasma-desktop Eating RAM ?
Nov 25, 2009I have Fedora 11 64bit installed and using KDE with all the updates . I noticed that after a few days of work the plasma-desktop process is eating abnormal quantities of memory - resident size can grow up to 1 GB, by then KDE gets so unresponsive that you have to restart the session anyway.
I don't use desktop effects and no plasmoids either (even got rid of the folder view of desktop), the graphics are Intel 82Q35 Express Integrated Graphics Controller with the default (intel) driver. I have dual monitor setup (1600x1200 and 1024x786), to get them work correctly I had to come up with a custom xorg.conf and xrandr (if someone thinks xorg.conf contents can be relevant, I can post them, too).
I've seen reports of memory leaks in versions 4.2, but none so severe as is my case.
Below is the top command (sorted by RSS) after just 5 days of usage, showing plasma-desktop consuming growing towards 500MB:
How to stop it consuming so much RAM? This is a real annoyance, since it slows down the whole machine because of induced swapping.

View 2 Replies View RelatedServer :: Memory Peak Caused Server Crash - Data Interpretation?
Dec 16, 2010Last week my server crashed. I'm trying to diagnose the cause.
This is the relevant error message in /var/log/messages:
Code:
I'm assuming that I can conclude, then, that apache/httpd was the cause of the memory leak?
Next, I've been tracking my memory usage. Using top, this is an average memory load level for my server:
Code:
I'd like to confirm if my understanding of this data is correct, because Plesk indicates that my memory usage is only 50% or less. (Though I have read a number of reports indicating that Plesk's measurements are frequently wrong.)
Top says: Of the 2,073,156K total memory, 1,982,572K (95.63%) is being used, 90,584K (4.37%) is free. Of that sum, 421,948K (20.35%) are being used as buffers. Additionally, of the 2,096,472K of Swap, 60K is used, and 887,700K (42.34%) is cached.
My questions: Is my memory actually being 95% used? Or is the buffered quantity (20.35%) not a use of physical/virtual memory? (i.e. is it disk usage?) Does the amount of cached Swap influence the percentage of physical/virtual memory being used?
In other words, who is correct? Plesk says I'm using 40-50% of my memory, whereas top says 85-95%.
Server :: Deadlock In NFS4 / Shared Servers Suddenly Stop Responding And Cant List It From Debian 5 Server?
Jan 4, 2010I am connecting servers using NFS4 the shared directories are on servers running Debian 4 while the one who read from them is Debian 5.0.3. The problem is one of these shared servers suddenly stop responding and you cannot list it from Debian 5 server, also df hang, and the web application that is using it does not respond to requests that use this shared directory since it is blocked. Then the load on the server start to increase until the server cannot respond (over 90). I have found many entries in the syslog that refer to this like:
ma25555 kernel: [1200285.732919] nfs: server 10.xxx.xxx.xxx not responding, still trying

Ubuntu :: Log Files Eating Hard Disk Space?

My main problem is that when I dual booted ubuntu onto my laptop, I had vista already installed, so I only set aside 20GB of hard disk space for ubuntu, which seems like more than enough to me. What's going on is that it says I have used all my space and only have one GB left, when the only thing I have on my computer are word files and necessary installs like flash player, compiz, avant, etc.When trying to hunt down what was using all my space, first I checked out the disk usage analyzer (some pics from here in):theres my hdd with 1/19 gb remaining here's a breakdown of my home folder, showing that it's not using very much at allhere's my filesystem, now we can see that all the space is being used in the folder: /var

CentOS 5 Server :: Put A MySQL Database In A Server's Memory?

Because this involves risks (unless there's a way to read from the memory and write to the memory AND disks?), so I'd prefer that the DB gets copied automatically every hour or so to the local disks.
