I have 6gb Ram. Bios is recognizing all of it. Ubuntu 9.10 i368 is only recognizing 2.5 of it. I am new to linux and have no idea what the problem might be. I have run hardinfo and it only sees 2 gb as well.
My specs:
NVIDIA 680i
intel core 2 quad extreme
6 gb corsair 800mhs (2x1 and 2x2)
Geforce 8800gts 320mb sli'ed with a 9800 with 1gb
Running Ubuntu 9.10 i368
I have a server for virtualization (Xen) and when I do a free -m it does not show all the memory (which should be 64GB), it shows 32GB (a considerable difference, isnt it?).
My hardware is a Dell R410 server:
Dual Xeon 5530
64GB DDR3
4x SAS 500GB in RAID 10
I tried to compile Xen 4.0.1 but I can't solve a compile error that it gives me (if you want to take a look: [URL]) that is the end of the compilation including the error. But, I installed Xen from yum directly after reformating the HD and it works fine now.
My kernel version: 2.6.18-194.26.1.el5xen x86_64
CentOS 5.5 64 bit
[root@server1 xen-4.0.1]# cat /proc/meminfo
MemTotal: 33554432 kB

I have a Red Hat 5.3 virtual machine that has 3GB memory. I just upgraded the memory to 4GB, however when I run free -m it still only recognizes 3GB. Is there something else I need to do?

At the moment, top shows all the RAM is taken, (NOT by cache), but the RAM used by the various processes is very far from 16GB.I have seen this problem several times, but I don't understand what is happening.My only remedy so far has been to reboot the machine.

I'm trying to install deluge via ssh and my vps has 512mb ram and is only using 11% of it prior to running the code.
I have had a fresh install of Ubuntu 9.10 and installed some software after that.Since third some, some process is eating half of my memory.I have checked processes running in system manager but everything is normal.Maximum is consumed by compiz which is about 26 mb, seems very normal.I did restarted my computer several times, and in the start for 5 mins, its fine after that again my cpu fans runs at very fast speed and my one cpu is used up 95 % (I have dual core).Please help me out, this invisible thing is driving me crazy.I am attaching my htop screen shot (sorted by cpu %), now the cpu is not used by completely but fan is still struggling hard and fast.

I am calling the insertNode() function with seq = 'MISSISSPPI$' and alphabets = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ$'
Code:
Weird behaviour I should mention is that when I check for NULL pointer in node->child[index], the unassigned values are not null anymore, they point to arbitary memory.
we found that if we use 'top' to show the memory usage of a server (SuSe Linux 10), we can get virtual memory usage as well as 'Resident memory' usage. For virtual mem or a particular process, it is around 1.1GB, which is large but for resident memory, it only consumes 300MB. Are there anyone who knows what the differences are? I would also like to know whether the difference (1.1GB - 300MB) = 800MB are actually available for use by other applications in the system.

View 2 Replies View RelatedI 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?
View 1 Replies View RelatedI am writing an application that wants to access periphals registers outside the standard (allowed) memory area.
Doing so gets me "segmentation fault".
I know, this is natural behaviour.
One way of getting around this is writing the module which has to be loaded by linux. I will consider this some time later.
For now, I want to come to some quick result and allow linux or gcc compiler to write to those memory areas of periphals. Is there a direct way to do so?
Is that possible that SHM shared memory is counted as cache memory on Linux with kernel 2.6.18?If find it really odd since this memory is not file backed, but I have a piece of code that loads data using shm_open+mmap, and it generates an amount of cache memory in /proc/meminfo that corresponds exactly to the amount of shared memory (I load that data from a file but I am using posix_fadvise(fd,0,0,POSIX_FADV_DONTNEED) to ensure this file is not cached and I made sure that it is working as expected). As far as I know SHM memory was not tagged as cache memory with kernel 2.6.9.If it is the case it is really unfortunate since normally cache memory can be considered to be part of the "available" memory since it can be flushed promptly but this is clearly not the case with SHM memory... Is there an easy way to get the total amount of used SHM memory on a system?
View 4 Replies View RelatedThis is my first post in these forums. I'm still quite new to Linux (using Mint 9) so please bear with my not-very-articulate question(s)When I boot up and open up a tty terminal I get a message saying "Memory corruption detected in low memory." I've done an extensive google search about the issue and it seems not uncommon. I ran a memtest with no errors returned, so I'm sure that there's nothing really wrong with the memory; apparently it's a bug in the kernel that's causing this.

View 7 Replies View RelatedI have been setting up a vps I got out with bhost.net, with CentOS installed. I've been learning and have set up everying I need with the exception of ftp/sftp.
Using yum I installed vsftpd and ran into problems, thinking it was something I might of done I did a fresh install of CentOS and I still recieve the same problem on a fresh install so it is nothing I have done to the server.
The problem is when connecting via a sftp client I get an out of memory error. This error is listed in the putty faq ( url ) under A.7.5, there is a brief explaintion of the cure under A.7.6.
there is mention of a login script but I don't know where this is located. I'm a novice at Linux but by no means incompotent when it comes to computing.
i just downloaded Ubuntu 10.10 onto a USB key and am attempting to instsll it next to Windows XP. The Ubuntu install wizard has giot to the point where i have already chosen my language and asked it to install upgrades as well, when i click "Foward" it only displays two options:
1) Erase and use entire disk
2) Specify partition manually
It is supossed to give the option to "Install along side other operating systems". This option is not being shown -si what do i do?
I am trying to install a fresh install of Ubuntu 10.10, but I am finding it is not recognising my only HDD in the machine. It is working because I am running Windows 7 x64 on it.
Here are my machine specs:
CPU: AMD Athlon 64 X2 5600+
Motherboard: XFX MI-A78U-8309 GeForce 8300
Graphics Card: NVIDIA GeForce 8300 + 8400
HDD: WDC WD5001AALS-00L3B2 ATA (~415GB)
The installation knows when my IDE drive is plugged in, but I want to install the boot sector in the WDC drive.
WUBI also fails to install on this current drive, though can setup the boot sector OK.
I installed the "recommended" graphic driver that pops up at top right and once I restarted the laptop, my graphics card no longer works with Ubuntu.

This printer worked great with XP on another computer. I have done all the updates to XP and it seems to be working just fine but when I go to the printer set up, it is not showing up. I have tried it where I plug in the printer while Virtual Box is running, but it didn't seem to make any difference. When I plug the printer into the usb port, Ubunto starts searching for the drivers but the Virtual Box doesn't.

I am trying the 10.4 version from last months APC DVD (I have used 8.4 (liked it) and 9.4 (failed to install) and I am trying to install it on my spare rig to see how it all goes.
System Specs:
Intel E6850 @Stock Speeds (normally OC'd to 3.2GHz)
G.Skill 2GIG DDR2 800Mhz RAM
WD500GIG SATAII Green HDD
Gigabyte P35 Motherboard (latest Bios)
Nvidia 9600GT Palit Sonic GPU
I boot disc from post, goes through the 1st 3 steps, select time zone etc and it wont find my HDD but it will find my USB mem stick when its plugged in.
I will keep fiddling in the bios to make sure that I have everything correct (it works fine when I installed w7 about 2 hours earlier)
I am installing it without dramas on a old P4 1.6GHz s478, 512mb Ram, 40GIG IDE and a old Geforce MX460 GPU and its at 53% so I know that the disc / version is good.
Since I upgraded to Ubuntu Natty, dvdFab has not recognized any DVD I insert into the drive. The program loads through Wine with no problems, and the disk is mounted by Ubuntu, but no dvd drives are recognized by dvdFab. I guess it will be a conflicting setting or something, but I would like to know if there is a solution, because my DVD player is knackered and only accepts DVD5's -not double layers any longer.

View 9 Replies View RelatedI currently am dual booting linux mint and windows 7. My only hard drive is partitioned in two, one for linux mint and one for windows 7. I installed linux mint with a usb bootable.
I want to replace my linux mint with ubuntu, however, my the usb bootable ubuntu isn't being recognized. I restart the laptop with the usb inside, but it just goes to the grub screen that lets me choose between linux mint or windows 7. The boot order has USB in first position as well. I used the usb creator as suggested on the ubuntu downloads page to create a usb bootable too. I've done this installation before with both ubuntu and mint... but now it's not working.
I tried "sudo update-grub" within linux mint with the usb plugged in, and restarting afterwards, but I still can't see the usb in the grub screen.
I managed to get the older, weaker box on the net and running simply by plugging in the Belkin N-wireless adapter, discovering the Network Manager icon (this really should also be accessible from the system pull-down menu), left clicking to see all the local networks, selecting mine, and inputting the security key, and rebooting. Voila!)However, on the newer, more powerful box, the network Manager gives me nothing but "Wired connection" at every boot (there is no such connection), I created a wireless connection under the settings (accessed through create VPN settings), but the Manager sees no wireless networks. Reboot solves nothing Network Manager is not seeing anything, I suspect that the card although powered by the USB, is not being seen by the system.
