I think it might be where you have very short curves or lines and the node at the ends engulfs the line causing the multipipe component to fail. Or where lines meet at very shallow angles.

I posted a similar topic [here](https://discourse.mcneel.com/t/strange-multipipe-subd-result/116527)

@DanielPiker has posted a good explanation of the Multipipe Inputs somewhere but I can’t find it.
