Ubuntu :: Memory Usage Steadily Increases Until Restart OpenGL Apps?
Aug 6, 2010
I use an ATI card with proprietary drivers and my memory usage in ideal situations when idle is around 600-700 MB. I use cairo-dock, AWN, compiz, gnome-do, and GNOME (w/o panel). My problem is, I have mysteriously increasing memory usage over time, which drops back down after I restart all my openGL applications. It can get as high as 1.5 GB. Looking in top, the weird thing is that when I sort by memory, I observe that none of the applications I am restarting, nor Xorg, use a significantly smaller percentage of system memory after being restarted. So what is going on? Does fglrx have some kind of memory leak? And is there a fix? In the last 10 minutes, my memory has for no apparent reason increased from 700 MB idle to 775 idle, and is still going up.
I was wondering why after a couple of days of my ubuntu server running, that it goes from starting off at 94mb of ram usage all the way up to 498mb of ram usage?
I was trying to have a go at installing MAC on my dell alongside Ub and W7. I copied the grub2 to the first part of my sda5 so as to put the mac loader in MBR.I have since repaired grub2 back to MBR.But now my beloved Ubuntu starts up then continuosly increases RAM usage till 90% then SWAP 90% even when no application is running!!
My computer has a 2.80Ghz Intel Celeron processor and 498MB of RAM and 3GB of swap space. When I use Fedora 11 the user memory increases over time and even if I quit all the applications the user memory still does not go down. It eventually gets so bad that have to restart my computer.
I was trying to get the status of memory usage and disk usage using sigar in windows and ubuntu. done this in windows by just copying the sigar library into jdk library. But i was unable to do so in ubuntu. I've copied the library to java-6-sun library but still can't run the program.
I play RuneScape most of the time i'm on the computer and i always keep an eye on the performance. Yesterday and the days before, everything was going good, cpu usage it was causing was between 30 and 60%, now it wont go below 70%. It's always 70-99% for some reason :s i have set settings for graphics to OpenGL (they were like that before too with no problem) and it started causing high cpu usage. If i set it to Safe Mode in graphics settings it gets 100%, I never tweaked the drivers, i have a NVIDIA GeForce 9600 GT, i have the opengl thingies installed along with my nvidia driver. Ubuntu 10.10 32bit.
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.
Whenever I try to start an OpenGL app in the terminal, I get a message to the point of "could not create GL context." It was working until around the last update. I know it's not a hardware problem because my windows partition works as well as ever.
I'm using Hardy Heron with the closed Nvidia driver with a Geforce 9800gt 'glxinfo | grep OpenGL' gives
I need to use FGLRX on my laptop, if I don't, either some OpenGL apps don't load, or the performance is poor.. With FGLRX the performance of the app is great and all work..
However, since Ubuntu 10.10, FGLRX no longer has "smooth" video.. And what I mean by that, even a simple DVD is dropping like 50% of it's frames every second with FGLRX. However, if I use the open source ATI driver, there is no video performance problem and even HD video plays fine, but then GL apps become a problem again..
In Ubuntu 10.04 FGLRX didn't have this problem. I did try to upgrade to the latest FGLRX 10.12, and every time I try on Ubuntu 10.10, I result with X not starting at all..
Here's the kicker though, the built in Movie Player with Ubuntu, works fine no matter which driver is used.. Now this wouldn't be an issue for me, but DVD's don't play right in that player, it runs like it's vibrating, but all other video formats work fine..
I'm at a loss. I gave up Linux a few months ago and wanted to try again, but once again, ATI is letting me down, and this is a laptop, buying a new laptop just because of the GPU is out of the question.
I am looking for free database that has low memory usage and innodb and memory like engins that has C API and support trigger and client/server support for using in embedded linux systems.
I'm running Debian Lenny with GNOME on a ThinkPad T43. Some OpenGL apps like the game Trigger run great, while others like Stellarium crash my system beyond recovery. I get a black screen, I can see the mouse cursor and move it at a very slow speed, but nothing else. I can't switch to a different terminal or restart X with ctrl-alt-bksp.
I assume that the problematic apps do not like the laptop's integrated graphics chip? Is there a way to know ahead of time what apps might be troublesome, before actually running them? I hate hard resets.
I am sure that all of us know the result of top command in linux. i want to get the value that the top command return as CPU usage, memory usage. so how do i do(programming relation)?
I've come across a really strange issue with one of my RHEL servers. The "free" command shows that 7019 MB of memory are actually in use by my system, but when summing up the actual usage (or even virtual usage like the example below) it doesn't add up - the sum is far less than what is reported by "free":
Is this normal? I check system monitor and the top most is xorg followed by compiz. When I first started with 10.04 few days ago it was around 300-500MB.
My 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.
I've been having some problems with Lucid; all my applications seem to be hogging memory like no tomorrow. Within about 15 minutes from booting the system, processes like Google Chrome, Nautilus, Python, Pidgin all start to take seemingly too large amounts of memory.
Chrome is the worst one, easily shooting over 200-300MB of my 2GB's of RAM. I would have reported this as a bug in Chrome itself, but my other applications seem to share the problem to some extent. Also: My colleague has identical hardware and identical versions of Ubuntu / Chrome, while he has no memory problems whatsoever.Currently I am running Chrome, Geany, Pidgin, Thunderbird and FileZilla. For this and itself, Ubuntu now consumes 1.8GB of RAM (that's including 500MB cached).
I am having a few problems with a red hat box involving memory usage. I have 64Gb memory and 'top' tells me I'm using 60Gb of it, but if I add up all the '%MEM' figures I get no more than 20%. Where is the other 80% ?
We have an ORACLE instance that is using shared memory but this is ceilinged at 45Gb. That means there is about 15Gb unnaccounted for . What utilities can I use on red hat to ascertain memory usage other than 'top' ? Any better ones, more detailed, looking at shared memory etc and swap ?
I like a lot of the last Ubuntu editions, but my computer is a little old, and Ubuntu becomes slower each edition to me.
I get a AMD Athlon 2 GHz, with just 512 MB of RAM memory...
I tried to customize my last installation of 9.10, but i just mess up with the OS. Well, I googled for informations about reducing memory usage, as well others speed-ups but all them are a bit older. Does anyone know any resource about this?
Until now I just disabled startups programs, but i really want is remove packages and everything that I don't use.
One thing thats get me up set sometimes is that I run Win XP pro under a cryptographed partition, and even yet its very fast in my PC. I even tried Windows 7, and its was faster than the Ubuntus I installed.
When I'm using the 10.04, there is a lot of memory used by cache, specially Gnome...
just installed ubuntu 10.04.1 after using ultimate for abit but having sound issues which i thought could have been os based.Sound works fine from boot and continues fine until i open options and try to configure my mic settings, i get like maybe 5 secs to make adjustments then all my sound dies totally. The icon then shows as speaker with 3 lines next to it and within the configuration for sound my mic hardware vanashes. I cannot get any sound until i restart my computer and so cannot use apps like skype which i do tend too use alot.
I'm trying to understand the performance of my machine and memory usage just isn't adding up. When I run top it will typically show 301M of 308M used but the total of everything in the RES column is no where near 300M and the total of %MEM column isn't more than 20-30%. So how do I figure out what is using all the memory? Then is there some way to control it to optimize performance?
I am a bit worried about my linux vserver box. No more memory is left. To investigate this issue, i was looking at "top". But it deeply confuses me. It seems that no more memory is left, altough the process list in top never adds up to 100%
Memory of my Linux database servce is all used up. I first noted that this morning and rebooted the box. 5 hours later, it saw used up again. I want to find out which process is responsible for using most of the memories. What Redhat Linux utility can list processes sorting by their memory usage, like the Windows task manager?free and vmstat - summary but not for each processtop appears to be infomative, but sum of non-zero %MEM never add upp to 100
in this example, my memory 993.4 MiB memory is said to have 575.9 MiB of it used and 163.4MiB of my 2.8 GiB swap memory used. but in my processes tab, the most memory hogging program is 98.3 MiB, and Pidgin, 25.9 MiB, and 18.9 MiB, 14.9, 6.2,6.1,5.2,3.4,3.3,1.8,1.8,1.7, etc. I'm certain these don't add up to 575.9 MiB so where is all this extra memory usage coming from?
