General :: No Swap Usage - Slackware 13
Nov 29, 2010
I'm using slackware about a month now and two days ago I checked to see the usage of my RAM and I saw that there was no swap, no used, no total, nothing! (how can this be?) swap -s returned nothing, I checked fstab and there was swap there so I entered the line about swap:
"UUID=6ea9269a-6bf7-4486-b481-a54dd3bde314 none swap sw 0 0"
I believe it' s correct. I checked after restart with "free" and the total was ok but used is 0. I copied about 5 GB to see what would happen and still nothing. RAM was nearly full but still no swap used!

I have Ubuntu 10.04 installed on my PC with 1GB of RAM and 3GB of Swap partition. But the machine gets hung or reboots itself when the usage is even marginally higher. This is the output of "free -m" for Swap:
Swap: 2908 11 2897
I have tried increasing the swappiness to 80, and this not made any difference. I believe the RAM is taking up all the load and none of the pages are going in to the swap. Hence the slow response and the frequent hung system. I know this is an old PC but Windows XP (installed on another HDD) runs way better on the same configuration.

No matter what I do, the SWAP usage remains zero all the time. Is there anything I am missing? In the following case (see attached screenshot) I am running make on the kernel that I downloaded. The CPU usage is understandable. But what is the use of Swap when its never used. [URL]. I am on Kubuntu natty. My partitions are as follows:
Kamesh@Galaxy:~$ sudo fdisk -l

We have several clusters used for high performance computing. The cluster nodes have 48GB memory and on each there is 2GB swap available. What I would like to avoid is the usage of swap as long as there is enough free memory or empty the swap as soon as there is a free memory. I thought that this could be achieved by setting the swapiness to 0, but although it helped a bit, it still didn't solve the problem completely. Even with swapiness set to 0, my memory usage looks like this:
total used free shared buffers cached
Mem: 48264 35534 12730 0 19 99
-/+ buffers/cache: 35416 12848
Swap: 2055 1286 768
So the system is using ~1.2GB of swap even if there's ~12.7GB free memory.

I have a netbook and one of the suggested optimizations was to reduce the use of swap.I've noticed on my desktop and conventional laptop that it is quite usual for the swap file to be used even when memory usage is low (25% of available memory).I'm looking for some advise on the best way to set up a conventional desktop or laptop as my understanding is that the use of a swap file will slow the system responsiveness down. Can I use a version of the above to improve performance and reduce swap usage?

How to reduce the cached swap from the server?
[root@CMS-UAT ~]# free -m
total used free shared buffers cached

-/+ buffers/cache: 1842 6143
Swap: 12479 4721 7758
[root@CMS-UAT ~]#
My server is showing swap usage of 4.7 GB.

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.

For some reason, if I leave my Linux box running for several days, the swap space and RAM slowly fill up until my system is so slow that it takes around 15 seconds just to open a new tab if Firefox (Iceweasel, specifically). I have 512GB RAM and almost a gig of swap; how on earth does it fill up so much? Even if I close all my programs, there's still over 600MB swap used and all RAM is full. I've included a screenshot of 'top' running just about two minutes after I closed all my running programs.
(Before I closed it, I had only 71MB swap free.) I know that Linux is supposed to make good usage of RAM, but isn't this over the top? Is there a way to force it to use only required memory with no or little extras kept in RAM? Just thought I'd add in the fact that I'm running Xfce as opposed to KDE or GNOME in an attempt to have a smoother running system on my old hardware. Also, what's the "VIRT" column?

I am running Apache 2.2.3 on a CentOS release 5.3 (Final) with 100 Sites. I've notice that Apache is making my server Swap around 200 MBs.
"http://www.xxx.yyy.zzz/server-status" doesn't show me too much to, so I am looking the behavior of specific httpd process.
ProcessID "18753" is the one for "http://www.xxx.yyy.zzz/server-status" in my browser.
This command show me (In KBs) how much virtual memory is that specific process using:
# /etc/init.d/httpd start
# grep Private_Dirty /proc/18753/smaps | awk '{ print $2 }' | xargs ruby -e 'puts ARGV.inject { |i, j| i.to_i + j.to_i }'
3012
... Running this command a lot of times it gives me the same output, but suddenly...
# grep Private_Dirty /proc/18753/smaps | awk '{ print $2 }' | xargs ruby -e 'puts ARGV.inject { |i, j| i.to_i + j.to_i }'
21708
Something make that process (and all the others httpd process too) to use a lot more memory!
Part of my httpd.conf:
# Timeout 120
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 3
<IfModule prefork.c>
StartServers 5
MinSpareServers 5
MaxSpareServers 20
ServerLimit 256
MaxClients 256
MaxRequestsPerChild 100
</IfModule>
<IfModule worker.c>
StartServers 2
MaxClients 150
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0
</IfModule> #
My server is running Mysql 5.1.34, vsftpd 2.0.5, BIND 9.3.4-P1 (as slave). I couldn't found anything running in the specific time that httpd processes start to use that much memory.

My monitor tools indicate that the percentage of swap used is more than the ideal , so I want to calculate which process is consuming from the swap. I tried the following but it didn't help be 100%
#ps -eo vsz,rss,pid,args | sort -n
How to accurately calculate which process consuming from swap, just the swap no ram + swap!

On one of my servers the "free" command tells me that a lot of swap space are in use. What I'd like to do is to determine which processes have been swapped out. I tried issuing "top" and sort by the "swap" column, but this doesn't seem to provide correct values - when performing the same excersize on another server with close to no pages swapped out, the sum when adding the swap value for each process greatly exceeds the swap usage reported by "free". So how do I go about determining the swap space used for individual processes?

Nagios had alerted me that the server had a very high load average exceeding the critical level (17+), when logging onto the server I found that all 4GB of the swap was in use despite the fact that there was 15GB+ of free memory (and that's not even including memory from cache and buffers!) Because it seems all heavily used pages were being stored in swap, the I/O wait on the server became very high, and 4 kswapd daemons were taking up nearly 100% available CPU. This did coincide with an error reported by Bacula during a backup job while changing to a bad tape...
From /var/log/bacula.log:

Well to cut a long story short, I fixed the problem by disabling the swap partition with 'swapoff'. After about 30 mins all the swap was freed and the server went back to normal. I don't dare reactivate the swap partition and unfortunately as this is a live server which currently has no fail over, I can't reboot either
Server Spec:
4 * Dual-Core AMD Opteron(tm) Processor 8214
32GB DDR2 ECC RAM
RHEL 5.5, 2.6.18-194.11.3.el5 SMP x86_64
Running many KVM VMs (All CentOS x64) and kksmd is used.
bacula-dir Version: 5.0.0
IBM Tape Drive using lin_tape module version 1.34.0 according to modinfo
And before anybody asks
# sysctl vm.swappiness
vm.swappiness = 10

I was trying to have a go at installing MAC on my dell alongside Ub and W7. I copied the grub2 to the first part of my sda5 so as to put the mac loader in MBR.I have since repaired grub2 back to MBR.But now my beloved Ubuntu starts up then continuosly increases RAM usage till 90% then SWAP 90% even when no application is running!!

I wanted to dual-boot Ubuntu and slackware, and use one swap. Well, I had Ubuntu installed and used installed slackware, and the boot hangs when I try to boot into the latest kernel; it says it's waiting for a UUID = (some random characters. I tried to enter a recovery mode for the latest kernel, and I couldn't even log in as root or my log in.

I got two problems. Problem 1 the sound is kind of sketchy..I thought the sound card got blown. But I heard my friend got sound on it again before we put Slackware on. Next I left him to install it while I went to class. I don't think he put a swap in. The computer is painfully slow and it can't even switch users because it looks like the ram got murdered or something. My Questions are how to test / get a working sound card. I did do the alsamixer I think the command is and turn the volume levels up yet I don't hear anything.
As far as the swap partions I don't there is one but I am not sure how to look / check to where if he made it to small or not at all.

While this is the second notebook I've had the luxury of running Slackware on, I have never used the the suspend to RAM / swap functions so all of this is new to me. With this new notebook and new installation of Slackware 13.1 I decided to give it a shot as it's definitely a power sucker. The machine is a Lenovo W510 with an NVidia graphics card running KDE. When I tell KDE to go to Sleep (RAM suspension) it looks like it does so properly by blanking the screen and pushing things to RAM. Is there a way to verify that Sleep is working? Anyway after unlocking the system my mouse pointer is no longer visible, however it is still active as I can hover over items to reveal their popups.
At this point none of my conky displays are transparent anymore, nor are they actively displaying stats. The windows I have set to display with 88% opacity are no longer as such and are completely opaque. It is as if all the custom window settings are ignored. If I move the the mouse towards the bottom of the screen the screen starts to go crazy with this rainbow of colors across the top of the screen and the only way to get out of this is to press Ctrl-ESC to bring up a System Activity window. I have not tried Hibernate yet as I would like to get this resolved first. Is Slackware 13.1 supposed to be able to Sleep/Hibernate with no special configuration and creation of scripts provided that the system can handle these functions?

Slackware 13.0, about to install it. I do have an existing Ubuntu installation with a roomy 5 GB of swap.
In the installer of Slackware, what should I do to use this swap?

after my friend dismantled my laptop, to clean out the fans, heat sinks, etc, I've noticed a few odd things, most of which have been fixed.But now, upon booting up, I'm using way more RAM than I should be using. Before, I'd boot up, start Openbox-session (which autostarted two instances of conky, tint2, gnome-panel, cario-compmgr, volumeicon, jackd, and wicd-client, and set my wallpaper), and I'd be using about 150MB of RAM, but now I'm using about that much before I even start my xserver, and when I boot up OpenBox (no session), and start conky, I'm using about 300-350MB. I start up Chromium, and it goes up to about 600MB immediately, then creeps up to around 900MB (which is ridiculous. Before the dismantle, the only time I'd ever been using that much is when running a game, or 464574568 tabs in Chromium.) And when I close Chromium, RAM only goes down to about 600MB.
While compiling my kernel, and with four tabs open in Chromium, my RAM usage went up to 1.80GB (which is also ridiculous, again I've never had that much used).what the hell is going on here!? :| is it even possible for some hardware issue to effect RAM usage?

Did a fresh install of 13.1 using lvm for the first time. I created swap in the logical volume but forgot to add it when I ran through the install. Do I need to just add an entry to my fstab and then swapon -va?

I have a system with 2G of memory and swap memory of 4G.
This is the output from :
PHP Code:
How could they do to the memory cache to be used as much? Because, occasionally, swap is used and note that the system could use the memory cache does not swap ...
Slackware current 64 multilib.

Currently running Slackware64 13.1 on a notebook and for the most part everything works fine. Only problem I am running into is with hibernation, where sometimes it will go into hibernation without a hitch and sometimes it will stall after blanking the screen and never turning off. For the most part pm-suspend.log looks fine every time, whether it goes into hibernation or not. My current system has 12GB of RAM and my swap partition is roughly 12GB. For the most part my RAM usage right before going into hibernation is always under 1.5GB with maybe 600MB floating in the swap partition. Could the size of my swap partition be too small even if RAM usage is nowhere near max?

I use the follow command to create a encrypted swap:
Code:
bash# echo "cryptswap /dev/sda5 none swap" >> /etc/crypttab
and edit the 'fstab' file :
Code:
/dev/sda6 / ext4 defaults 1 1
/dev/mapper/cryptswap swap swap defaults 0 0
That's work fine, but I found the permission of '/dev/mapper/cryptswap' is like this:
Code:
hello@world:~$ ls -l /dev/mapper/cryptswap
brw-rw-r-- 1 root disk 253, 4 2010-05-28 12:55 /dev/mapper/cryptswap
Other users can read the file '/dev/mapper/cryptswap', does it harm the system's security ?

I was reading this tutorial & it shows swap at the beginning of drive. [URL]
Although I've already installed slackware & put the swap at the back of os, I would still like to know the benefits and purpose of putting at the beginning.

For some reason after I close firefox , firefox-bin keeps running and it eats more cpu than when firefox was open, a lot more. Same thing with seamonkey, seamonkey-bin keeps running after it is closed.
Attached are two pictures ,
1) While firefox is running: notice the low CPU usage
2) Firefox closed, CPU is almost 50%

I'm looking for a simple way to monitor and log my internet bandwidth usage. Not total network device usage, just internet usage.Something that provides a simple chart of daily, monthly, and yearly usage, but ignoring all bandwidth on my internal LAN.I notice several possible tools, such as vnstat, ntop, iftop. Yet all of them seem focused on tracking the entire network interface. I want to ignore LAN usage. I do not really care about LAN bandwidth.iftop seems intended only for on-the-fly usage and not cumulative logging. I can't tell whether vnstat or ntop can be configured to log only internet usage rather than all traffic through the network device.
I do not want to log every connection like squid. The utility should only log stats on a daily basis, but also be able to display cumulative totals from those daily entries.I don't need DNS resolution, port monitoring, etc.I prefer something that runs in the background as a service or daemon, but can provide statistics quickly with a terminal window. All I want is to view total daily, monthly, and yearly internet usage. Perhaps even pipe the output to a local email each day too.

I often swapped window managers between fluxbox kde and gnome back when I ran ubuntu to suit my needs. When I installed slackware, I picked KDE because of the convenient app suite. I don't wish to uninstall kde but I'd like to be able to pick which environment I use when I swap to a GUI. Something like a flag, startx --fluxbox.
