We study the anti-de Sitter/conformal field theory correspondence with boundary conditions AdS{sub 5}xS{sup 5}/Z{sub k}, where the Z{sub k} acts freely but breaks all supersymmetry. While there are closed string tachyons at small 't Hooft coupling, there are no tachyons at large coupling. Nevertheless, we show that there is a nonperturbative instability directly analogous to the decay of the Kaluza-Klein vacuum. We discuss the implications of this instability for the strongly coupled dual field theory, and compare with earlier studies of this theory at weak coupling.
