Here are the same bug with mine described: [URL]
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 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.

Code:
QImage *MyClass::f(QString filename) {// Open image
QImage *image = new QImage(filename);

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.

int *buffer;

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.
Is there any link where i can get information about below?

View 1 Replies View RelatedI'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 can confirm my machine's GLX version is 1.4, and I definitively get the slow down problem, however, after running in a terminal:

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 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.
View 2 Replies View RelatedI'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?
View 3 Replies View RelatedI just ran into a weird problem with a CentOS 5.5 64-bit server running VirtualBox 3.2.8 (I would run Vmware Server 2.0.2 if not for the well known fact that Vmware doesn't care about its Server line anymore and it doesn't run on CentOS > 5.3 without major splits). I currently have two guests in that VirtualBox setup, a CentOS 5.5 64-bit and a Fedora 13 64-bit. The CentOS 5.5 guest shows less memory available than configured. If, for example, I give the virtual machine 512MB of memory the guest OS only recognizes 380MB. If I give it 768MB it only recognizes 637MB, and so on. I don't have that problem on the Fedora guest - 1024MB configured, 1024MB available.

how to reach full RAM capacity? CentOS is installed on HP DL160 G6 server and memory module positioning is correct.
When using TOR it is recommended that you disable javascript and all other scripts because they can be used to detect your IP, defeating the purpose of TOR.
But there are some sites that simply do not work without javascript. Is it possible to keep all javascript functionality but disable just the functionality that is used to leak your IP?
The problem seems to be a memory issue. Seems the problem only started happening after the last few updates. I have tested the memory with memtest and both servers passed. There hasn't been any new software put on the servers for over 12 months.

I ma porting an application from SUSE 10 Professional 64-bit to CentOS 5.3 x64 version. We have set the /etc/php.ini as in old server and set the maximum memory limit to 5GB (yes! We have ample of memory) for the process.It was working fine in old server but in new server, the Apache log always showed that it failed to allocate more memory for the application.We noticed that the error coming out while the application uses up to 1GB memory.Just wish to ask if the PHP in CentOS 5.3 has any restriction on memory usage?

View 1 Replies View RelatedI have xen kernel on a 5.4_64 though it seems to have always done this regardless of version. When I add a virt the control set shows the total machine memory minus what I just allocated to the new virt. This also shows up in the system monitor as total available ram. Problem arises in deleting and making new virts. The memory never reappears as usable after deleting virts. So now after testing several different setups I'm down to 1.4 gigs showing available on the dom0. What can I do to recover this lost memory? I've searched, read, looked every where I could think of and there just doesn't seem to be any information about deleting virts only adding them.

Cent OS 5 support 8 GB Memory on a 32 Bit System?
View 4 Replies View RelatedI have a custom-built machine running CentOS5.3 final x64. It has an AMD Dual-Core 64bit 3GHz processor. I have installed 8gb of DDR2 memory in the system, which the BIOS correctly reports. However, CentOS only shows ~5GB. What happened to the other 3??! I am using the machine as a VMWare Host, so every gig counts.Here's what meminfo says:
# cat /proc/meminfo
MemTotal: 5976376 kB
MemFree: 39552 kB
Buffers: 43204 kB
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.

I just don't know how centos is using the memory but... I took a look at httpd conf, may be I've missed something when I type "free mem" in ssh the memory is increasing while I'm playing one video, flv and mp4 on my site. it is increasing each time I play a different videos either the same.
