We exhibit a pseudoeffective R-divisor D_\lambda on the blow-up of P^3 atnine very general points which lies in the closed movable cone and has negativeintersections with a set of curves whose union is Zariski dense. It followsthat the diminished base locus B_-(D_\lambda) = \bigcup_{A ample}}B(D_\lambda+A) is not closed and that D_\lambda does not admit a Zariskidecomposition in even a very weak sense. By a similar method, we construct anR-divisor on the family of blow-ups of P^2 at ten distinct points, which is nefon a very general fiber but fails to be nef over countably many prime divisorsin the base.

The diminished base locus is not always closed
