Ubuntu :: Memory Leak / Some Process Eating All Memory
Jan 29, 2011
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.

Linux 2.6.18-238.9.1.el5
Apache 2.2.3
MySql 5.0.77
PHP 5.3.3
Samba 3.5.4-0.70.el5_6.1
Problem: my server eats up all the memory in the box after a few days. My guess is it has something to do with these processes:

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'm currently developping a program in C++, using Qt, for an embedded board (SBC9261).It works well but crashes after some time, due to a system memory overload (my program uses more and more memory until 100%, when it crashes).I've been able to figure out the source of the memory leak :The function f is called by my program every second. f instanciates a new object (a QImage from the Qt lib), does a bunch of processing on it, and returns it to the calling function :
Code:
QImage *MyClass::f(QString filename) {// Open image
QImage *image = new QImage(filename);

root@XXXXX:~# uname -a Linux myserver 2.6.18-194.11.4.el5 #1 SMP Tue Sep 21 05:40:24 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux I'm having serious memory leak issues on a server running CentOS. Running 'top' I can't find any proccess with an unusual memory usage. Is there any other way to check what is using this memory? Right now it shows that I have 4.8GB of RAM used, but top shows only few proccesses, one with 4% and lots of 0.0%.

If I have a centos linux server, how can I stop a user on the server from eating all the memory and swap space memory, maybe due to a poorly written script, infinite loop etc?

I need to write a small program that eats away at availabe memory. I need to creaty a memory leak to test how other programs cope. I need to run this program on linux and see if the available memory is decreasing.
So I have done:
Code:
int main()
{
int *buffer;
while(1)

I can confirm my machine's GLX version is 1.4, and I definitively get the slow down problem, however, after running in a terminal:
Code:
grep "object bytes" /sys/kernel/debug/dri/0/gem_objects
grep: /sys/kernel/debug/dri/0/gem_objects: No such file or directory
What am I doing wrong?

I dont know if this issue has already been solved, or if there are other threads dealing with it, but Im quite desperate with this bug that has been annoying me since I upgraded from 9.10 to 10.04.
Firs I thought it would be GEM related, but Im using a proprietary graphics card, so thats not the way to solve it. I experience the problems a memory leak provokes, mainly that, as time goes by with the laptop turned on, the system needs more resources to execute simple actions, and it freezes too many times. Plus IBUS will, suddenly, stop working (I still don't know if it is related or not), and, most of the times I log in, Notification Area 2.30.0 will load with errors.

I have installed Debian Lenny today from netinst cd. It all went good, hen I installed some basic utilities, daemons and libraries like dbus, hal, libgtk2.0, libasound2, alsa-utils, htop (for checking system load). Then I installed X.org with commandaptitude install -R xserver-xorg xserver-xorg-input-mouse xserver-xorg-input-kbd xserver-xorg-video-intel xinit xterm twmI used -R to pull less dependencies. When I ran startx X Server started, and I got on twm. But when I checked on htop, my memory usage was 175MB, and before starting X Server it was only 25MB. Why is X Server using so much memory on Lenny? I also have Debian Sqeeze on a different partition, it uses so much memory with all gnome services running+ iceweasel and amsn.

I have 4 gigs of ram and xorg goobles up 70+% in a matter of an hour or so. I'm running a java app with lots of 2D graphics, firefox, pidgin, and one other java app. I recently upgraded to KDE 4.2 and got dual ATI firepro 3700 cards running 3 22" widescreens. The memory gets eaten until my java app crashes.
I'm using the fglrx driver as it seems the radeonhd one doesn't recognize the firepro 3700. Can one only have a single KDE4 version on the machine. I would like to be able to swtch back and forth between 4.1 and 4.2 in order to troubleshoot without all the downloading and installing in yast.

I'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:
[Code]...
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'm afraid I have a huge issue with my newest Fedora 14 server. I recently migrated to Fedora 14 from Centos 5, which was very stable, but had ancient packages and libraries and my users were revolting...The machine is a HP ProLiant 360 G7, with 12G RAM and 6 SAS drives in RAID 5.After I migrated to Fedora 14, I noticed that for some reason, during the course of about 24 hours, all usable RAM "disappears" and applications are forced down to swap space. Needless to say I didn't have this issue on CentOS.
The server does heavy IO as per it's function (it's a heavily loaded file processing server and user simulation computing station among other things, which causes lots of random IO), so I thought it may be the cache, but then I realized it cannot be - because obviously Linux will use onyl "unused" RAM for caching and frees it up as soon as an app need it. Then, I thought to check the "slabtop" to see what's going on in Kernel memory. Unfortunately I don't have the screenshot from the time just before the latest crash, but there's a certain value displayed by slabtop, which slowly, byte-from-byte creeps over all available RAM, eventually forcing applications down to the swap. This is malloc-64, and as you can see from the bellow copy-paste, it's building up again even now...
Code:
Active / Total Objects (% used) : 9118075 / 9153600 (99.6%)
Active / Total Slabs (% used) : 152157 / 152157 (100.0%)

I installed Ubuntu 10.4 and everything works great "out of the box"! I didn't install any drivers.blem, a major one...When I type "top" right after a reboot, around 1GB of RAM is in use. After a few min it grows to 2GB, even 2.5GB for no reason. Luckily, my machine has 6GB of RAM but it's still a major issue for me.I read on another forum another user with the same problem on the same Lenovo machine and he solved it by installing the newest driver for his ATI device. I don't have ATI, but I have the impression that I can solve my problem the same way. Do you have any idea what driver my cause that? I checked the Intel site for a new Intel HD graphics driver but they don't have ones for Linux.

Xorg takes 700+ mbs of ram, then in matter of hours it fills the swap and then system basically stops responding or whatever. And because its constantly allocating, it degrades perforamce horribly.Interesting thing is I never had this problem before, recently one of my ram modules broke (2+2 GB) and now I have only one, but it still doesnt explain the memory overuse. Windows 7 works perfectly fine.

My server is keep on hanging So I have rebooted several times in the last couple of weeks, the system is eating more memory and the usage is keep on increasing and at particular time it became saturated and my server hungs. I could not find which process is eating more memory. I have used the below commands to check if any process is eating more memory but no luck. No such process are using high memory.
1) Top
2) ps -eo pcpu,pmem,user,args

I updated several packages on one of my servers on Dec 21st and have been seeing excessive swapfile usage since then. The problem process seems to be httpd which in our environment runs a subversion server as well as serving a number of php pages over https. At present I am having to bounce apache approximately every 5 days as it has used all 8GB swap in that time.
[Code]..
Of the updates listed as installed, the only one that looks likely to affect apache is glibc. Looking at the stats from sar -r I can see swap usage increasing by approx 3% (of 8GB) every hour.

I'm using Fedora 15 with Gnome 3 on a 32 bit laptop. I noticed that there seems to be a huge memory leak issue with Gnome shell. When I restart it, it is around 20 MB. But it keeps rising, and after around eight hours, I noticed it was around 250 MB! I found a solution online that said to simply restart the shell if the gnome-shell memory consumption becomes too large. While this is fine as a temporary solution, I am looking for a permanent one. Is there a way to minimize/prevent the memory leak other than waiting for the next version of Gnome 3?

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?)
