Random Rebuild Errors

Hi I'm spiral pattering a set of holes around a pole.

Sometimes I can create 2 sometimes I can create 11 copies but no more.

There is very simple geometry.

Rebuild zero-thickness geometry errors randomly appear in the 2 - 11 range of copies.

I'd like to go beyond 11 to the height of the spiral.

No idea whats going on here.
