Trouble with snappy and boundary layers

Hi!

I have a problem with boundary layer addition producing strange "blobs" on edges of the geometry. The snapping works well but the "blobs" appear after adding layers.
I'm attaching images from the stl file and from the snapping procedure, both with and without BL.
I have also attached blockMeshDict and snappyHexMeshDict.
We have managed to produce more complicated meshes before with these settings and the .stl file seems to have high quality??

Unfortunately the mesh is quite large (5M cells).

Platform:
linux64

Version:
1.5.x

Thanks
