 Posted: Fri Oct 08, 2004 8:06 pm Post subject: Running out of Ram... |
 |
|
Afternoon all,
I have a Compaq Laptop (r3190US), with an AMD64 3400+, and 1024MB of PC2700 ram. For some reason I keep running out of ram when I'm running games (such as UT2004, or Doom3 demo), so the program starts cache'ing into the swap. Lagging up the large games. I can't figure out why though... It seems /dev/shm takes up 506MB (that's from the ram). So half of the ram goes to to there. Is there a way to limit this? I think it's suppose to resize itself, but it doesn't seem to resize.
Some more info:
Kernel 2.6.7 |

Weird. What's in /dev/shm/ that takes up so much memory? I've never seen any program use that space on my system.
You could try different kernel sources. ck-sources for example includes a patch that tries to prevent unnecessary swapping. |

There is nothing in /dev/shm. It's empty. So I umounted it... I don't know what this will do but Doom3 runs just fine now =-). From what I hear it's used by GCC, but that's all I know. man shm doesn't bring anything up - its just kind of strange. To my knowledge it should be able to resize itself when it's not in use - or more memory is needed. But it's not doing that.
I'm going to try a new kernel, but maybe not till a bit later. I've been run quite stable with my 2.6.7. *sigh* I this is bugging me |
