To complete the picture: not only was our network swamped, I realized tonight that the NameNode/JobTracker was running on a 99% full disk (it hit 100% full about thirty minutes ago). That poor JobTracker was fighting against a lot of odds. As soon as we upgrade to a bigger disk and switch it back on, I'll apply the supplied patch to the cluster.
