Congruences between Hecke eigenforms have a long history. Most of these have a simple modular representation theoretic interpretation. Serre developed a systematic approach to predicting the exceptional congruences that arise when the corresponding Galois representation is tamely ramified at p. We will discuss a generalization of this phenomenon in higher rank. This is joint work with Le Hung, Levin, and Morra.
