I have a Red Had EL5 server. Free -m shows total mem: 3042 and used mem: 2903. However, when I run a top or ps, there's barely anything using any memory. how I can identify what is using all this memory?
View 2 RepliesI'm running several SHOUTcast server instances and a WowzaMediaServer instance on a CentOS machine. I'm experiencing a memory leak problem, but I can't figure out which processes are eating memory.
TOP command reports as follows:

Something misterious to me (I'm still a Linux newbie) is that TOP reports a total of 7.5GB used ram but very small percentage for single process (0-1%). Memory consumption starts at 1GB/8GB after reboot and in three days running gradually increases up to 8GB. I'm practising with Linux, but I still miss a lot to understand what's happening on my system. For instance, are there linux kernel logs saved somewhere that I can look at?
I am using malloc and frees a lot in my program. It shows its allocated but when i remove it doesnt show as the memory is removed(I am using the top command to view VIRT memory usage). If this continously grows what would happen to my program (Will it go out of memory?)

I am looking to buy some memory for my netbook. Currently I have 1 GB of DDR3 memory. However, the specification says that 2 GB of memory is the max. However, when I do the following it says that 4GB is the max:

I have a computer with 16GB of ram. 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 am calling the insertNode() function with seq = 'MISSISSPPI$' and alphabets = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ$'

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 9 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?

Does anyone have any idea what I should check for? Is there's a specific quoting method I need? In a Bash script I'm pulling quoted text from a file with cat then writing that same string (hopefully quoted!) to a variable. I have a single set of hard quotes (') in my text files presently.
This 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 think this is not the right place for this post, but i can not figure out how to post a bug. i am talking about the permissions of: /tmp/orbit-root. please don't tell me now "don't" log in as root if you once login as user root from the login screen the permissions of /tmp/orbit-root are set to: drwx root but if log out the permissions are not set back / or the entry will be deleted. this will end for the next login as a normal user that you will get a bulp of error messages. easy to reproduce. this is not a feature - it's a bug.
View 1 Replies View RelatedI've been troubled by the high amount of RAM that is used by my Ubuntu desktop. Before I installed Ubuntu 10.04 (desktop, 64-bit) my system used around 500MB of RAM when no applications were open (just cold boot into the GNOME under 9.10). But when I installed Lucid, I've noticed that my used memory is now reported as 1GB or more as soon as I log into the system.
I want to figure out what is using all the extra RAM but I can't seems to find the culprit. I looked at all of the processes and numbers just don't add up. I exported the list of processes into a file and summed up the memory used by every process in a spreadsheet. The total came to around 700MB. Yet, both System Monitor and "free" reported the time that system was using over 1GB of memory. This means that at least 300MB of RAM are used but not by any process, at least as reported by "ps".
