I have deleted all the results of photorec and various other large files and removed them from trash but it still has not freed up any space. Also, my firefox no longer has back/forward functionality which I'm sure would be fixed by a reinstall but seeing as I have 0 space, I can't really do that. Any thoughts?

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.

After checking my tmp folder I found out some strange hidden and unhidden folders of programs that I have not used or downloaded. After removing each one using sudo rm -rf some folders insist on re-appearing, and after a reboot all folders are back.
Moreover, trying netstat -l, found that many of these files are in listening state.
How can I permanently erase them?
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 4 Replies View RelatedI 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?

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.
How to reduce the cached swap from the server?
[root@CMS-UAT ~]# free -m
total used free shared buffers cached
Mem: 7985 4146 3839 0 3 2300
-/+ buffers/cache: 1842 6143
Swap: 12479 4721 7758

My server is showing swap usage of 4.7 GB.
While booting Linux it takes ages for 'enabling swap space'
I have allocated swap space twice that of the RAM.
Is there a way to fix it? What should I do to avoid this in the future installs?
clarify me with ulimit output and memory limit?
ulimit -a output:
core file size (blocks, -c) unlimited
data seg size (kbytes, -d) 1572864

View 2 Replies View Relatedthe method for freeing up space by deleting old kernels is made to sound very simple: go into Synaptic, select the outdated kernels, mark for complete removal, and Apply. Easy. But . . . when I mark a particular kernel for removal, Synaptic also wants to remove a lot of other things, some of which do not bear version numbers and seem generic. I am, to put it mildly, very leery of just telling it to go ahead, lest I end up losing things I should have kept and having a dead or at least crippled box.
Say, for example, that I mark for Complete Removal the line linux-image-2.6.22-15-generic; when I go to Apply that one deletion, I get a laundry list of to-die files that includes:
linux-generic
linux-image-generic
linux-restricted-modules-generic
linux-restricted-modules-2.6.24-27-generic
linux-ubuntu-modules-2.6.24-27-generic

I am using Ubuntu 10.10 and 10.04 on two different computers.I have the same problem with both .... when I delete a file on my hard drive or a removable drive I dont get the space back even after I empty the trash.The file is gone and deleted but its as if its only hidden from me seeing it and still sitting on my drive.For example when I have files on a thumb drive and I delete them and try and put new files on there it will tell me I dont have enough disk space even though all files have been deleted, the only way for me to get the disk space back is to format the drive.I have now realized I have the same problem with my hard drives, I delete files but I dont get any space back, eventually I will have a full hard drive but no files on there

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
