Memory leak
Hello! (I am sorry for my bad Eanglish)

I think, that in the driver there is an memory leaks.
Use of memory by a X-server grows in due course though I do nothing,
has simply logged-in and do nothing.

Right after start of a server approximately 7 %
For 5 hours -- approximately 50% (%MEM)
pixmaps 17509K (xrestop)

Athlon 64 3000+
512 MB
GF 6600

SuSE 10.2
Xorg 7.2-26

Re: Memory leak
Well, for start you could read this:

I see you have 1.0-9629, but current new stable nvidia drivers are: 1.0-9746
Try upgrading.

Re: Memory leak
You should also read the driver README which discusses why this behavior is not a bug, and is expected.

Re: Memory leak
I found only:

Q. OpenGL applications leak significant amounts of memory on my system!
A. If your kernel is making use of the -rmap VM, the system may be leaking
memory due to a memory management optimization introduced in -rmap14a. The
-rmap VM has been adopted by several popular distributions, the memory leak
is known to be present in some of the distribution kernels; it has been
fixed in -rmap15e.

in README. This ?

Re: Memory leak
No, see the FAQ section with the question:
Q. Why does X use so much memory?
