What is meant with offscreen memory, main memory + card memory or smth =
else?

xscreensaver is running, so some 3D applications are possibly run when
it activates. The box is usually on all day.

Do you mean the XFree86.0.log or an strace log?

Can you please describe how memory (both card and main memory) is
allocated and released for 2D and 3D applications: What puzzles me is
that if I start with a fresh X everything is OK, but after the problem
occurs I have to exit X to be able to run the application again. It is
not sufficient to terminate the application to get back to the same
state as as when starting anew.=20

Possible causes of the resource shortage can be:
1. The applications do not return memory when exiting.
2. X cannot reclaim the memory when the appications exit.
3. There is a memory leak somewhere.
4. Something else??

Thanks,
Svante
