I was getting the same error pretty frequently with a file I was
working on (few times a day). It was a 3d grid of points, made by
dividing a stack of planes. The file was relatively heavy since I had
points determining the radii of spheres on these points, with a number
of test conditions for distances and such. Seems to be consistent with
what people are experiencing, but I would change sliders and large
amounts of data would have to recalculate and no crash, but i would
pan or something do something else with no real changes, and I would
crash...

Don't know if this helps...

Totally unrelated note, but I've been trying to figure out if there
would be a way to create a varying cull pattern, governed by an input
function or something. The idea would be to create the affect of a
distorting grid, by only placing geometry on every Nth grid point and
then shifting that series somehow... Any ideas would be appreciated.

Thanks!
