all memory used?

ferradura · 04-13-2007, 06:57 AM

i am having a problem with an app that keeps failing saying that there aren`t enough resources. i assumed it was a memory problem so
i ran top to check on the system ...how on earth may i be using this amount of memory? any ideas on what the prob is? I am running kde, cause it`s @ work, but if i find no solution, i am moving my jwm configs to work too.

Code:

top - 12:53:24 up 21 min,  1 user,  load average: 1.32, 1.04, 0.63

KDE is using all your memory. What do you have in there 512? KDE typically on my systems when I used it ate up around 450MB alone with a browser open. Try Fluxbox or some other lighter WM, its much better anyways....imho

Linux and memory ... funny thing

. Point is, if memory is there, the system will use it and not free it until requested otherwise. Meaning fast re-use of valid and still residing data is always possible. You can see that in the value of "cached" memory, i.e. in your system more than half of your RAM holds data "just in case". You can see that also regarding your 2 GB swap, of which a mere 12 kB are used.

In summary: I don't think it is a memory problem here and now.

What is your application? If it needs huge amounts of storage it might either be during allocation in the RAM or on the hard disk. Some more info needed...

Agreed.
Whatever it is you're short of, it ain't likely to be memory.

Huh? How did you figure that one? Only 9.6 % of his total memory is used according to top, look at the numbers in the %MEM column and I don't see kdeinit at all...

Code:

Mem:    514068k total,   504188k used,     9880k free,    10436k buffers

The program is a small module from GRASS. I have used it before and never had such problem, only today...
I have started with init 3 and the result is a bit better

Code:

top - 15:56:31 up 3 min,  1 user,  load average: 0.77, 0.33, 0.12
Tasks:  65 total,   4 running,  61 sleeping,   0 stopped,   0 zombie

Mem:    514068k total,   244524k used,   269544k free,     4804k buffers

but i keep getting the same error:

Code:

X Error of failed request:  BadAlloc (insufficient resources for operation)
  Major opcode of failed request:  53 (X_CreatePixmap)
  Serial number of failed request:  505
  Current serial number in output stream:  513

Do you have 8, 16, or 32 bit color depth? You could try other values. For example:

Code:

startx -- -depth 16

JZL240I-U · 04-16-2007, 01:15 AM

@ferradura Look at my first post, there I gave the reason for the numbers. Truly in use is the amount in the column "MEM".

This seems to be a problem of X-(server). Did you change anything recently in the xorg.config?

SteveK1979 · 04-16-2007, 06:06 PM

Hi,

The command

Code:

free -m

will give you a much better idea of memory allocation on your system.

You should see something like

Code:

             total       used       free     shared    buffers     cached
Mem:          1002        477        525          0          8         76
-/+ buffers/cache:        392        609
Swap:          976        128        848

The 'free' column in the 'Mem' row should be the actual amount of free memory in your system. Check out the man page if you want to find out more, or search on LQ.

Cheers,
Steve

Ya,
me too when I was using KDE,
it was easting up almost all of my memory.
I too have only 512 mb of ram in my
box.So now I'm using fluxbox and it's
only using less than 70 mb of ram while
idling.I'm still trying to get used to
fluxbox but at least my pc is light on memory!
Oh if you need to still use KDE then my advise
would be to make a swap partition least 1 gig
big.That way when your pc needs more memory it just uses the swap.

i am having the same problem with CRUX 2.3, xorg 7.2 and blackbox
i am confused because i have used the software before and never had such a problem..

JZL240I-U · 04-19-2007, 01:01 AM

So you re-configured X? Do you still have your old xorg.conf? If so, try to use that...

No, i am using the same configuration, just changed the version of xorg, but the problem remains.
Are my config values causing the problem? I am using the i810 driver, but my chipset is i815.

LazyP · 04-19-2007, 11:21 AM

I suggest you all chill! There is no way for KDE to use 512MB of RAM. In fact it hardly gets over 256MB unless you are doing sth serious. The original poster didn't give enough details of the memory usage. Most of the RAM is probably innocent disk cache. It could be some incompatibility between different X versions. Does your app list a specific X version to work properly?

I don`t think so, because i am getting a similar error with xorg 7.2. And it`s not depth related i guess.
GRASS mentions nothing about x versions...
Again

Code:

X Error of failed request:  BadAlloc (insufficient resources for operation)
  Major opcode of failed request:  53 (X_CreatePixmap)
  Serial number of failed request:  502
  Current serial number in output stream:  512

It`s not memory related, the first post of "top" shows the cached memory i think.
