Server :: Debian 5.0.6 Too Much RAM Usage
Oct 30, 2010
I'd been using Directadmin on my Debian 5.0 machine earlier . I had 1GB ram and a lot of memory was used up. Sometimes even the OS crashed as the programs couldn't allocate memory. I increased my RAM to 3GB but still the RAM usage sometimes just flow up to 1GB although normally DirectAdmin doesn't use more than 200MB . Restarting the server fixes the issue but then it climbs up again and comes down to a 200-400MB again by itself. Cached Memory was also being too much and sometimes even Swap Partition gets used up .Just to be sure that it's not the Bugged OS, today I installed the latest Debian 5.0.6 Net-inst on my machine . I allocated just 128MB of ram to it because it was just a testing machine. I installed it without the swap partition since I thought I will make a swap-file if it is required. I did not even update the OS rather I just installed Openssh-server and everything else was default as in Debian 5.0.6 . When server started, only 20MB ram was being used .
I just logged into my server afer about 5 hours and saw 112 MB ram being used out of which 91MB was cached. I haven't installed anything so why is this happening ?Why is this happening when I just installed the default Operating System and didn't even run an apt-get update on it.I think my previous operating system with Directadmin was also having similar issues.

I've come across a really strange issue with one of my RHEL servers. The "free" command shows that 7019 MB of memory are actually in use by my system, but when summing up the actual usage (or even virtual usage like the example below) it doesn't add up - the sum is far less than what is reported by "free":
Code:
[root@server1 ~]# free -m
total used free shared buffers cached
Mem: 12011 7946 4065 0 4 23
-/+ buffers/cache: 7919 4092

Last weekend i've set up my first headless ubuntu home file server and torrent downloader with ubuntu 9.10.Very cool but CPU is way too fast for a home server: P4 HT 2.8Ghz, unfortunatly it has only 256Mb of ram, so no X server and no VNC (old HP office pc) At the moment memory usage is only 40Mb without X server. Besides SSH works just fine Few questions i can't seem to find answers to on google:What is a good CL network monitoring program?mething similar to htopUbuntu 9.10 has a lot, about 20-30, console-kit deamon instanses running after boot each using some memory that i can't spare.

I am looking to probably make a home server act as a backup for most of my data but also as a media server. I want to host all my music and videos for the most part on the server and then regardless what computer I'm using I could listen or watch. (Another question would be could I have itunes find my music on the server and play it).
But anyway, from people with home media servers, what kind of bandwidth usage do you go through a month? Comcast (ISP) limits me to 250GB and I'm thinking this is enough for moderate usage, I just want to make sure before I start the project.

I was trying to get the status of memory usage and disk usage using sigar in windows and ubuntu. done this in windows by just copying the sigar library into jdk library. But i was unable to do so in ubuntu. I've copied the library to java-6-sun library but still can't run the program.

I'm running into a problem where my system is running out of disk space on the root partition, but I can't figure out where the runaway usage is. I've had a stable system for a couple of years now, and it just ran out of space. I cleaned some files up to get the system workable again, but can't find the big usage area, and I'm getting conflicting results.For example, when I do a df it says I'm using 44GB out of 58 GB:
Code:
[root@Zion ~]# df -h
Filesystem Size Used Avail Use% Mounted on

I'm getting DDoS attacks on my server, and I need to block all the attacking IPs.But for that I need to know which IPs are attacking me.I was thinking that I should log the bandwidth usage per IP so I can tell which IPs are using excessive bandwidth.How can I achieve this? I'm using Ubuntu 10.10.

I just installed Debian 6.0 on an older box, the CPU is an AMD K6-2 (with 3D Now) 500MHz, with 512Mb of on-board memory.
I installed this with the LXDE as the desktop environment and it includes a CPU usage graph (colored green) on the LXDE panel, by default. Based on my past experience with Linux, LXDE runs faster on this hardware than XFCE or Gnome.
When I use a web browser on this system, whether it is Iceweasel or Chromium, the CPU usage spikes up to 100%.
I believe Gnash may have something to do with this. I removed gnash which also removed browser-plugin-gnash and went to the same sites afterwards, the CPU usage then dropped considerably.
I realize that the CPU is somewhat slow (compared to today's processors), but why would Gnash (and probably by extension, Adobe Flash Player as well) use up all the CPU resources?
The installed video card is an nVIDIA GeForce 2 MX400 (PCI) with 32Mb of on-board video memory. I have another video card that could be used, a 3dfx Voodoo3 2000 PCI with 16Mb of on-board video memory. which I believe is also supported by xorg. The monitor is a Sceptre X9G-Naga III LCD, 19", resolution is 1024x768 (the maximum listed in the settings).

I'm running a recursive DNS server on Ubuntu Server 10.04 64bits and Bind 9.7.0-p1 and having issues with memory usage. The named process memory usage keeps increasing from about 500Mb to 4Gig inside of a couple of weeks. If I don't restart Bind in the mean time the swap fills and performance gets very bad.

Just noticed from the "top" command that one of my least heavily used box is swapping excessivly by a program called setroubleshootd. Following is the top section of the "top" command sorted by Swap used for both boxes. Also tried checking it out to see if there's a "service setroubleshootd restart" but when I checked the status I got the following.

We have an internal application which takes below 10% cpu usage normally. However sometimes it hit above 85% or more (and stays there) causing the server to become very slow. Currently we have to monitor this manually, kill the process and manually start it.
command / script that will kill the process (using pid will be the best option as i think) when it reaches 85% or higher
(I saw another question that suggested to use monit but I have to get this done using the standard commands available in the current installation - RHEL5)

I am using qmail in my office. I am noticing this for more than a month. It is my daily routine to check the cpu utilization using top command and by using top different processes can be viewed. the apache process after 1 or 2 days shows cpu utilization of 100%. There is no affect on the server whatsoever of 100% because mail server has 2 processors of 4 core, i think so that may be the reason. Can any one explain why is this happening. What i do after that is i restart the httpd process and cpu utilization comes to normal. What are the reasons behind this and how to solve this permanently.

I've installed my debian sid about one month ago (first xfce, next gnome) but noticed that it's kind of really slow. The upgrades take ages, launching (and using) firefox takes so much time,... In comparaison to my ubuntu, archlinux (on the same computer) or previous installation of debian there is clearly a problem somewhere.Today I tried to do a "top" sorted by mem usage : 3.5% xulrunner-stub, 2.1% dropbox, 1.4% aptitude (doing upgrade), 1.4% clementine,... nothing terriblebut still I've 2.7Gb or RAM used (more than 50%)

I use a Debian Squeeze system running off a flash drive, i.e. based on a custom Live image running in persistent mode. It runs great and I am grateful for the existence of Debian . However, I have a question. A lot of the machines I use this pen drive on are quite old, often with 512 MB RAM and old processors. I specifically built my system using XFCE and lightweight apps off an initial live image using the standard-x11 package list (basically just Xorg with drivers and the base system). At first things ran very well, blazing fast even on the oldest systems and could comfortably run Firefox along with LibreOffice side by side (I need LO as all of my colleagues use Word docs, often with track changes, which Abiword can't handle properly). However, over time, I've found that memory usage has risen, tot he point where Firefox is now automatically killed on the older systems every time I start LibreOffice.how does one figure out why memory usage is going up? I've checked for inessential services and turned them off with "insserv -r". I've used only lightweight apps, as mentioned before. Are there other general tips on reducing memory usage?

Just made a strange discovery, visiting the website: [URL] .... with iceweasel within university's network makes my computer almost unusable. htop's output indicates:
USER: 'root' CPU: '98%' Command: '/usr/bin/X :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch'
What this meant to be and/or how this could be circumnavigated?
