hello Denis,

I had the same problem some time ago, together with the nvidia guys, I found 
that the issue is a memory leak in the X libs.
Adding

    Option "NoRenderAccel" "true"

to your XF86Config's Device section should fix that for now.

Note: This does not disable the 3D-, only the 2D rendering-acceleration 
(that's what they told me)
