Ubuntu :: Vlc Using High Amounts Of Memory?
Apr 30, 2011I just installed Kubuntu 11.04.
I ran VLC and it brought my PC to a halt.
I attached a picture of memory usage from htop.
Why do you think VLC is using so much system resources?

Hardware :: Why Dmesg / Grep Memory Gives Two Different Physical Memory Amounts
Oct 20, 2010I am monitoring physical memory in a server I administer, and my hardware provider told me they had increased physical memory size to 4Gb... However, using several tools (free -m; top; dmesg | grep Memory; grep MemTotal /proc/meminfo I discovered that I actually have 3Gb, not 4... But, my doubt comes from the fact that dmesg | grem Memory tells me I have 3103396k/4194304k available The first number is effectively 3Gb, but the second one, is 4! so, why I am looking at this two different numbers?

Jul 11, 2010My problem seems to be very simple, it's high memory usage. I occasionally will use movie player to watch a few shows and I use firefox as well. My memory usage starts out real small about 500 mb but after using firefox lightly and movie player it jumps to almost 2 gigs and this is after they've been closed what gives? I've attached an image so you can see what I'm talking about.

Oct 18, 2010I have a kernel module that I am trying to do a phys_to_virt() and then perform a memcpy to the returned virtual address. The problem that I'm having is that my module crashes during the memcpy when trying to do this on a physical address in high memory. Do I need to need to perform some kind a mapping operation on high memory address for this to work?

General :: High Memory Utilization By System?
Nov 11, 2009I have a server running samba process and there are about 70 samba users connected at a time. The system has 4Gb of memory and it seems each samba process is utilizing only 3352Kb of memory.
When I run the command
pmap -d (pid of samba)
It gives as:
b7ffa000 4 rw-s- 0000000000000000 0fd:00003 messages.tdb
bfe46000 1768 rw--- 00000000bfe46000 000:00000 [ stack ]

mapped: 33384K writeable/private: 3352K shared: 20504K
But when I run the top command, it results as below:
Tasks: 163 total, 1 running, 162 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.9% us, 4.9% sy, 0.0% ni, 93.3% id, 0.8% wa, 0.2% hi, 0.0% si

Swap: 2097144k total, 208k used, 2096936k free, 2487636k cached
Why could the system be utilizing such high memory? By the way, the server is not running other processes. The samba version running in it is 3.0.33-0.17.
Fedora :: Setroubleshootd: High Memory Usage After F13 To F14 Upgrade
May 11, 2011I upgraded from Fedora 13 to 14 over the network. Everything seems to have worked. The one problem after my install is that I have noticed that setroubleshootd consumes alot of memory.
[Code]
It doesn't take long for setroubleshootd to jump in memory usage. I can kill the process but it will start up again. I have tried disabling the service but it doesn't show up in /etc/init.d. # service setroubledshootd stop setroubledshootd: unrecognized service So I am not sure what I can do to resolve the issue with setroubleshootd besides killing it off every 15 minutes.

Ubuntu Servers :: Consequences Of Giving PHP Scripts A High Memory Limit?
May 28, 2010I have an Ubuntu server running in our small office. Among its many duties is report generation. It uses PHP and DOMPDF (a PHP library for converting HTML/CSS to PDFs for printing). PHP's default memory limit of 32MB is not even close to being enough to pull large amounts of data from the database and generate images/tables/PDFs with that data.
I increased the memory limit to 64MB and that is adequate for reports under 3 pages or so (varies based on table complexity, images, etc). If any user tries to generate a report longer than that, PHP just throws a "out of memory" error and doesn't make the report.
My question is: what are the possible consequences of increasing the memory limit yet again to 128MB or maybe even higher? The server isn't terribly powerful. It has 2GB RAM and 4GB swap space. I know that isn't much but this is a small office and at most I can only see two or three people trying to run reports at the same time. As for security, apache is currently only serving pages in the local network, but sometime within the next year I'll probably have it hosting a public website (currently using a hosting service). Is a high memory limit a potential security risk when exposed to the internet?
EDIT: Sorry, PHP's default memory limit is 16 not 32 as I said. Question still stands, however

Dec 20, 2009i have a car stereo that reads a USB drive with all my music on it, however to sort through the music it uses a method of finding folders containing music, then displaying them all in a list. i find this interface annoying because in order to sort the music by artist i have to go and manually move it out of the album folders by hand, this takes a long time for 11+ GB of music so i was trying to use the linux CLI to quicken the process. use a command like this
Code:
mv /media/usb/music/*/*/* /media/usb/music/*/
but for some reason this moves all my music into the last folder alphabetically in my drive, the music is all pre-arranged like this /media/usb/music/artist/album/song

Jul 16, 2010Sometimes I need to copy a huge directory to another directory (local filesystem), and usually I will use the "cp" or "rsync" commands. These commands are good, but depending on the size of the data being copied, the copy is painfully slow. I realize we are limited because of the hardware we have with it's limitations, ie, I/O speed, and the filesystem (which is usually ext3). Are there any other utilities that maybe not well known, but can handle copying large amounts of data? (mostly in the TB range)

View 1 Replies View RelatedServer :: MySQL Backup - Deal With Large Amounts Of Data?
Feb 15, 2011we've been trying to become a bit more serious about backup. It seems the better way to do MySQL backup is to use the binlog. However, that binlog is huge! We seem to produce something like 10Gb per month. I'd like to copy the backup to somewhere off the server as I don't feel like there is much to be gained by just copying it to somewhere else on the server. I recently made a full backup which after compression amounted to 2.5Gb and took me 6.5 hours to copy to my own computer ... So that solution doesn't seem practical for the binlog backup.Should we rent another server somewhere? Is it possible to find a server like that really cheap? Or is there some other solution? What are other people's MySQL backup practices?

Dec 8, 2009We're load testing some of our larger servers (16GB+ RAM), and when memory starts to run low they are kicking off the oomkiller instead of swapping. I've checked swapon -s (which says we're using 0 bytes out of 16GB of swap), I've checked swappiness (60), I've tried upping the swap to 32GB, all to no avail. If we pull some RAM, and configure the box with 8GB of physical ram and 16 (or more) GB of swap, sure enough it dips into it and is more stable than a 16GB box with 16 or 32GB of swap.
