 Posted: Sun Sep 12, 2004 7:02 pm Post subject: memory leak in xorg 6.8? |
 |
|
Using ati-drivers-3.11.1 I'm seeing this in free -m:
| Code: |
total used free shared buffers cached
Mem: 502 491 10 0 0 162
-/+ buffers/cache: 329 172
Swap: 0 0 0
|
using top and sorting per memory I'm seeing nothing that can account for that kind of memory usage, so something must be leaking.
I'm thinking it might be ati-drivers with the latest xorg, cuz I haven't seen this behavior before.
Anyone else seeing the same thing? |

The memory is being used. It's the way linux utilizes your memory (caching it for use with other programs, but relinquishing it when necessary).
If you do a search in the forums, you should find a very nice and informing post which gives quite a few details about how/why it's like this. 
I have 1GB of RAM, free -m shows:
| Code: | free -m
total used free shared buffers cached
Mem: 1011 785 226 0 111 543
-/+ buffers/cache: 130 881
Swap: 494 0 494 |
But using Torsmo (system monitor) I can see that currently, only 100+ MBs are in use. Don't worry about it. |

your currently using 130mb, which makes sense, especially if your using something like kde which does some light caching itself.
I'm using 329mb with basically nothing running.
I'm well aware of how linux deals with memory. |

If you use kde , startup Info Center
There you can see what how your memory used

Remember that the latest xorg with composite enabled gives each application its own area of memory to draw to. These are then composited together to give the final image.
You don't say whether you're using composite or not, but if you are expect memory usage to be much higher than without. Perhaps not *that* high though...

shared memory, not a big deal.

so can top, and unfortunatly I can't see it, which makes me think the radeon kernel module is the leak.

not using composite or loading the composite module on this box.
//edit, considering I've seen huge memory usage without it swapping now, I'm starting to think it might be Con Kolivas'es work on caching and memory that's causing the odd top output. And that I really dont have a problem here at all. |
