Crashes: Is it just a memory issue?
I'm starting to see a similar pattern of crashes with the first person shooter games Nexuiz and Unreal Tournament 2004 demo - much more so with UT. The graphics freeze, the audio may loop a little, and at first the system seems to have come to a screeching halt. I cannot immediately switch to a console via Ctrl+Alt+F# or kill the X-server, and there seems to be no harddrive activity. However if I give it a minute or two, I see various graphics corruptions and am finally able to get a console. I immediately run top and kill UT and X, but a short time afterwards my system crashes again, and requires a reset. I can't seem to ssh in from outside at any time after it becomes unstable.
Does it sound like this is a memory issue? I only have a quarter of a gig of RAM, and my friends say a game like UT would do much better with a full gig. Yet it's not as if my swap drive is even filled to half capacity, so I don't understand why a shortage of physical memory would lead to anything besides a slowdown. I've tried killing my normal KDE session and running it on its own uncluttered X server.
If you don't think this is the problem, then am I looking at bugs with the kernel/nVidia, or UT (and to a lesser extend, Nexuiz) itself?
AMD Sempron 2800
256 MB RAM
nVidia 6200 / 256MB
nVidia 7667 driver ( - actually I just upgraded to 7676 but have yet to test it)
I've seen a number of threads with UT related problems here, but none of them mention a random crash with no error message or log entry.
