oh no worries. its just the specific reference to the "Bi" parameter. i imagine its something similar though, as that does seem a tough problem to solve for any kind of sampling.

This is a smoothed, low-poly sphere with a diffuse mat and bump map. Rendered with 1.0.9_3
I'm also attaching the scene.
Not sure but it seems like yafray artifacts, managed by the parameter Bi
(Shadow ray bias to avoid self shadowing).
If i remeber good i posted (long time ago) a similar post at the kerkythea forum.
Isn't that just what ray_nudge_distance does ?

Ray nudge distance is to prevent floating point errors - it's the minimum distance two (tris? verts? sampled points?) can be apart, smaller than that and they're considered together (so no material -> air -> material, as an example).
