Thibaut updated CASSANDRA-2408: ------------------------------- Description: Hi, We had to replace a node with faulty ram. Besides the cassandra cluster getting unresponsive, we also observerd a "keys must be written in ascending order" exception on all adjacent quorum nodes, causing their compactation to fail. We had another node with faulty ram a week earlier, and it was causing the same errors on it's neighbours. A faulty node shouldn't affect the key ordering of adjacent nodes?
