I started using atol as convergence criterion with -ksp_norm_type
unpreconditioned. The value of atol gets updated every outer iteration.

I think something went wrong. Setting the block size to 4 and solving
for (u,v,w,p) the convergence degraded significantly. I attached the
results for a smaller test case that shows the increase of the number of
needed inner iterations when setting the block size via
MatSetBlockSize().

The system has indeed a one dimensional null space (from the pressure
equation with Neumann boundary conditions). But now that you mentioned
it: It seems that the outer GMRES doesn't notice that the matrix has an
attached nullspace. Replacing

	CALL MatSetNullSpace(CMAT,NULLSP,IERR)

with

	CALL KSPSetNullSpace(KRYLOV,NULLSP,IERR)

solves this. What is wrong with using MatSetNullSpace?
