strange line on texture

Hello everybody,
I’ve got a small problem here,


When you look closely, you’ll see a line going trough the carpet texture and I don’t get why it is there. I have only used procedural textures.

I don’t get why you haven’t attached your blend file. Do those who want to help you have to guess at your material settings.

I’ve attached it now, the file was too big at first.

It the texture tiled?

I don’t know how to tile procedural textures.
