How can I figure out which programs are using up swap space? My current memory usage is 2.9GiB out of 3.0GiB used(and I though I had 4GB, I need to check into that) and 1.3Gib of swap used.
View 1 RepliesI have a linux server top reports about 9GB of swap used:But I cannot figure where's it use swap, some google results said that top - O commad follow by p will show swap usage by process. But as shown in the above image, taking a brief sum of the SWAP column shows that > 10GB of swap is used, so where does the 9GB figure for swap usage come from? Top reports that about 96492kb of ram is used by buffers. Is there anything I can do to utilize this, instead of using swap?
View 1 Replies View RelatedWhile installing slackware64-current, setup cannot find swap space. This is an extreme case pushing limits with a huge GPT partition table. So there is probably some limit on the number of partitions, or partition number, the swap search looks for. Of 41 partitions I made scattered around the number range from 1 to 128, the swap space exists as partition 90. Maybe the problem is it can only check partitions 1-15 because 16 and beyond have to use a different device major number? When I do proceed with the install, /dev/sda90 is listed as a choice. FYI, so many partitions is planning ahead for a multi-boot system. The rest of the install went OK.

View 5 Replies View RelatedI'm interested in figuring out which programs on my machine are using swap, and how much each is using. I realize this can probably be done with top, but I am having trouble figuring how how.
What I've tried:
Start top
Press f (add column)
Press p (SWAP colum)
This adds a SWAP column, but the data doesn't seem to be correct. Top lists Firefox as using 582m of swap, but the header simultaneously reports that 0k of swap is being used.
Is there a better way to monitor swap usage?
a friend of mine recently installed Ubuntu in his Laptop however is running really slow. It's Dell 1520 so I don't think the computer is that slow. I think what the problem is that he doesn't have a swap space. ok, I could use GPARTED to resize the HD and create SWAP space but how can I tell the system to permanently use that space?
View 14 Replies View RelatedI have a rel 5.6 system that we just added more memory to.
1. What is the correct or best way to increase swap?
2. Can I remove the swap space later on?
3. How do you remove it when done?
Our rootvg only has 8G available to it and I want to be sure if i allocate anything out to it I can reclaim when done without having to rebuild the system.
We have to do a lot of data moves so we allocated extra memory to this VM system and now we need to increase swap. I did see several articles in google but they describe using a new swap partition, a swap file and increasing an existing swap space. I am still not sure what is the best way to go knowing this is a temp situation.

When we want to setup a linux system, there is a common a suggestion like set the swap space as twice as big than your physical memory, I want to know why do we need this and how is this suggestion come from?

Why is that?
Closest analogy I can compare what I want to, is like the `sync` command, which writes out all stuff in the disk buffers, freeing the buffers.Instead of disk buffers, I want to 'clean out' my RAM and SWAP of any/all junk that's accumulated in there over the time my PC has been up. I've long wondered about this, but never asked, though I recall searching around several times..When I first boot it cold and log in, the memory usage bar on my desktop is near zero, and the swap is empty. But after a week or 2 or 3 or more of uptime, and with Firefox always running with a dozen tabs or so at any given time, I end up with all the memory full or 'filled with cached stuff', and the swap space is filled to capacity.Curiousity: I blame Firefox for leaking memory, but even if that's still the case today (historically it was) can this all be blamed on Firefox? Or what-all causes this, besides Firefox- just..Everything?
Here's current stats:

So, 3.8 of 4 Gib of RAM is occupied, and the 1 Gib swap space is jammed full 100%. This must slow things down to some degree, yes? I mean, the kernel does have to keep track of this, right?Of course closing all the applications doesn't make a difference (not an appreciable one anyhow) and the only way I have found to start fresh is to reboot.
Wish a script which would delete cache content and remove additional files which have been downloaded via the internet and saved voluntarily by the user and files any thing other than those used by the OS in linux.Need a command which could make the execution of the above script possible before the shut down command is passed.

View 4 Replies View RelatedWhen i first installed ubuntu about 2 weeks i left about 30gb left for windows vista. I have not used vista at all so i decided to delete it and use the whole hard drive for ubuntu. I got the liveCD out and went into the partition editor on that (i had ubuntu,swap,vista in that order) and deleted the swap space and vista and increased the size of the Ubuntu partition to so there was only 4gb left for swap. I then booted up again from the hard drive and i get this message "one or mounts cannot be mounted" or something to that effect and it talks about the swap partition and offers to boot in recovery mode which does work.Once in recovery mode i go in and try and make swap partition with Disk Utility and i do that and it works. I go to restart Ubuntu to test it out and the same problem happens again, cannot mount swap ect. so i go back into Disk Utility and it now says 4gb Unrecognized instead of swap

How to add swap space?
View 5 Replies View RelatedI am currently writing some convenience methods for my terminal in my bash_profile and am sure if what I am writing is "the best way". I figure a good way to verify whether what I'm doing is right or not would be to find some source code of more established programs and see how they do it.My question then is, where can I find this code on my Mac? An example is, with Macports installed, where is the source code that opens the port interactive console when I type nothing but "port" in my shell?(I added Linux in the title even though I am on a Mac because I assume the answer would be the same for both)

I am currently running 32 bit ubuntu in my PC with 2.5 GB RAM, Intel Pentium Dual Core inside. I am coming to debian soon. I will be installing 64 bit squeeze. Now I have 3 GB of swap space. I do satellite image processing. Therefore what is the recommended swap space for me with the kind of work I do. RAM is in very small amount but as of now I have to stay with it.
Also I am interested to know would KDE be an overkill for my machine. Will I run short of memory when I start image processing?
I got back to my laptop after dinner and found a blank screen with one line of text saying something about running out of swap space - I tried all kinds of key combinations but nothing worked to bring the desktop back - eventually I pressed and held the power button to shut it down - I suppose this is Ubuntu's version of the "blue screen of death"?I went to System - Disk Utility to make a 2GB free space right after the swap space. Then I tried to make that 2GB free space a swap space partition but it came back with an error

View 6 Replies View RelatedI am using a Dell Inspiron 580 that I recently recieved as a gift. I wouldn't normally purchase a Dell, but I have no money and it my old computer was WAY past it's prime. After going through a miniature nightmare I now wonder how to create swap space for my ubuntu installation. I am running 10.04, 64 bit. I am having no problems, but I have no swap space. My computer is a new -Intel i3- with 6GB of ram; so I assumed I could worry about getting it installed, then set a swap file later. As I said, it runs well, but i don't feel comfortable with ZERO swap space.
When I installed Ubuntu I already had a problem because Dell had included 2 special partitions that are diagnostic and recovery. This didn't surprise me, but I want to make my system backup less than 100GB, so I shrank the "c:" partition to 100Gb and made the free space "storage":NTFS partition. After backing everything up (before messing with the partitions), I installed Ubuntu. Since I had created the backup that Dell asked me to (the very first time I turned the PC on) as well as my own system image I wasn't concerned.
Using GParted Boot disk I deleted the Dell "Recovery" partition and marked the "C:" drive (COS)) as active. I used a Windows 7 install disk to "repair" the bootmgr problem. Had to run "repair" twice, but it worked.
My question now is: why didn't Ubuntu installation say anything about a swap partition until I had already set up my partitions? I could easily give up a gig or two for swap space but I cannot make a swap partition unless I delete the Dell diagnostic partition (NOT the "recovery" partition; the other hidden one). I don't mind deleting the "recovery" partition because it is backed up, but I would prefer not to delete the "diagnostic/utility" partition, just in case. The 40MB is crap anyway.
It hadn't occurred to me that I would have trouble making swap space. I am used to windows (I am dual booting with GRUB BTW, if that matters) and the swap FILE doesn't need it's own partition. I understand why a separate partition would be better, but unless I can somehow create a logical/extended partition for swap, I need to know what else I can do.
I believe Ubuntu is a better system for many reasons, but little things like this do puzzle me. I am no engineer, or software designer, but I don't understand why I wasn't given an option, such as: You cannot make another primary partition; would you like to use a virtual disk/file as your swap space?"
