I assume you're using triangle-strips to draw the terrain? What is the result when you turn LOD / Frustum culling off? You haven't posted what method of LOD you are using...

Very hard to tell from that picture exactly what is going on, but it looks like a bug in your lod algorithm, where you are generating the triangles. It doesnt look like anything to do with frustum culling.
