I'm not sure where all the fluid is, but I suspect the contact regions are Meshing being overly sensitive with the tolerances. Can you confirm the surfaces between the annular volumes have a finite area? If you delete all of the contact regions you should be OK. But, you do need to check you have all the correct volumes in the domain.
