Parallel run runs into assertion about too many interior unknowns

[blattms]

I have not looked into this. It happens on a run with 32 MPI processes

flow: opm-simulators/opm/simulators/linalg/ParallelOverlappingILU0_impl.hpp:450: void Opm::ParallelOverlappingILU0<Matrix, Domain, Range, ParallelInfo>::update() [with Matrix = Dune::BCRSMatrix<Opm::MatrixBlock<double, 1, 1> >; Domain = Dune::BlockVector<Dune::FieldVector<double, 1> >; Range = Dune::BlockVector<Dune::FieldVector<double, 1> >; ParallelInfoT = Dune::OwnerOverlapCopyCommunication<int, int>]: Assertion `interiorSize_ <= A_->N()' failed.
