Try with more samples, the default is 3, you may need a lot more.
Try antialiasing.
Post a larget version, maybe not full size, so the problem lines are more visible. You
can send a 
full size part of the image: crop it around the problem area.

this is a small part of the image, i already used anialiasing but more
smaples is a good idea.
thanks!

that seems like a post-clipping problem (meaning that the colors get clipped to
be inside the 0-1 range *after* averaging anti-aliasing samples).  As far as I
know, there's no other solution than rendering it at a higher resolution and
then resizing it.
