kde4.2+xorg 1.6,memory problem

tas0s · 2009-04-28 17:40:05

I use kde 4.2.2 and xorg 1.6.My notebook has nvidia Geforce 8400M GS with the latest beta driver.
After ~10min of use, the X process binds ~200-300MB of memory
I tried with new ~/.kde4 and the problem remains(with no difference if kwin effects are on/off).
Now with ~6 hours uptime the X process consumes 955MB.
Also when the "memory leak" has already begun,if I try to execute nvidia-settings -q gpucoretemp(displays gpu's temperature),
I get this message:

Maximum number of clients reached
ERROR: Cannot open display ':0.0'.
ERROR: Unable to query attribute GPUCoreTemp specified in query 'gpucoretemp' (no Display connection).

What I can do to fix it?

My xorg.conf:

It seems your plasma bin is leaking (well not exactly leaking, but causes X to leak).

If you give a: xwininfo -root -children > list and then you read the list file it generated, I'm pretty sure you'll see a lot of " "Qt-subapplication": ("Qt-subapplication" "Plasma")" in there. For some reason the plasma process is spawning too many X clients and your X's sockets are all (or most of them) reserved by those clients.

This perhaps explains the large memory usage of X too.

I think I saw a blog post of Aaron Seigo discussing this problem and the solution but I'm not sure.

tas0s · 2009-04-28 19:49:48

Probably you mean this http://aseigo.blogspot.com/2009/04/plas … usage.html
Thank you again for your help!
Just one more silly question.Is anything I can do to fix it or I must wait for the next kde update?

Have you found an answer for this?

tas0s · 2009-05-04 19:36:55

Nope.I have installed kde 4.2.3 from testing with the same results.
I also try the same setup in sidux and the problem occurs.So it is not arch specific.
Now I am thinking to switch in gnome until kde 4.3 is out.
Sad,I really like the new kde.

newgargamel · 2009-05-05 09:32:55

you could also try to use latest QT from git repository as this leak is from QT lib.

tas0s · 2009-05-05 16:36:46

@newgargamel
Could you be a little more specific?
When you say the latest Qt,you mean this package :http://www.archlinux.org/packages/extra/i686/qt/,
but not from the extra repository;I must compile it from git?
(Any how-to or guide? )

thanx for your help!

foolosophy · 2009-05-05 20:23:09

He probably means this package from AUR: http://aur.archlinux.org/packages.php?ID=24093

The problem is that it doesn't compile in my machine. I tried but couldn't get a working PKGBUILD.

yes, this one but I'm not able to help you with building it, sorry. Here is the bug report regarding your problem: https://bugs.kde.org/show_bug.cgi?id=183191 You can also try to find a patch from the day Alexis fixed this problem(it would be the simplest way)

tas0s · 2009-05-09 00:22:49

I tried with kde svn and qt-copy from markc repo .
Set up the same panel layout etc..
The same problem again.
Xorg process memory consuption is rising.Too fast.
Right now, after 1-2 hours of use,it consumes 500+MB
So,the only solution I can think rigt now is:
a)new .kde4,no use of plasmoids and wait to see if the problem persists
b)gnome (no offence for gnome,but I'm using kde for ~2 years)

EDIT:
I forgot to mention that I have removed the digital plasmoid
from the panel as it is reported in the bug report but with no
change in memory consumption.

I read that it is not a problem of kde or qt, but it's a xorg 1.6 bug. just try to launch for example 100 copies of konsole or terminal or anything else, then kill them and see the information provided by top. Xorg doesn't empty the unused memory I think

tas0s · 2009-05-09 20:06:19

shagrath I think that you have right.I started ~20 instances of konsole.The memory consuption is ~450MB(before the konsole copies was ~290).Even if I closed all konsoles,the memory consuption remains 450MB!

The funny thing is that when this "leak" came up in my machine,the first think I tried was to downgrade to previous xorg+nvidia, with no results.
So here we are again!I'm going to try again with the previous version of Xorg and I will inform you.
thank you very much for your help!

EDIT:
augegr said that

after the output of some commands..:/

No change with the previous xorg (1.5).
So it is kde-specific or kde+nvidia specific
The nouveau driver when will be ready (for 3D etc)?

shagrath · 2009-05-10 17:37:37

tas0s, it's strange that previous xorg didn't help you. I was sure that it's a xorg 1.6 problem
I was trying previous nvidia drivers and even new betas - no effect. Now I don't know what to do too.

tas0s · 2009-05-10 18:39:44

So,you are facing the same problem?
The strange thing is that with new ~/.kde4.it takes about 5-6 hours or even more to see the memory leak.
But from the moment that memory leakage starts,in the next login(with restarted xorg-server) it only takes 1/2 hour!
Could be a corrupted file or something relevant (cache)?

I finally gave up/I switched to gnome
With my ram filled up,I was unable to run VirtualBox(WinXP) & NetBeans for my university assigments.
But I'm still searching for a solution

vi3dr0 · 2009-05-10 18:48:47

I did have the same problem about 2 or 3 weeks ago - X used up to 1.5GB of RAM.

It simply went away with one of upgrades

tas0s · 2009-05-10 19:05:31

@vi3dr0:
Are you using any plasmoid?Could you describe your setup?
I mean nvidia driver,xorg version,panels,plasmoids etc.
Even a xorg.conf would be helpfull
Sorry for the many questions,but I dont know what is the cause of the memory leak
I see that you are using kdemod..
hmm i know that kdemod4 is almost vanilla,so are there any differences in libraries?(ex.Qt)

shagrath · 2009-05-10 19:38:29

I just tried to switch to fluxbox. and I launched just about 100 terminals (not somehow connected to kde), xorg was occupying about 200 mb, then I killed my terminals, but xorg was still taking 200 mb...

tas0s · 2009-05-10 19:48:17

!?!?!
so its not kde-specific??
In gnome:
Xorg -> 36MB!!
Is anything common between fluxbox and kde4?

shagrath · 2009-05-10 19:52:06

tas0s, I don't think so. but maybe my memory leak is not connected with your memory leak

shagrath · 2009-05-10 19:55:00

by the way my X in that moment takes 26 mb. that problem appears when I'm trying to launch ~100 applications and then close them. fortunately, I don't need to do that.

tas0s · 2009-05-10 20:11:14

Maybe you have right.But the "terminal test":P gave me the same results:P
So is there anything we can do to limit down the possible causes of the leak?

I had this memory issue for about 4 or 5 days (using GNOME) and it simply gone away with one of upgrades.

Right now X is using ~200MB which I consider completely typical.
