Github user Parth-Brahmbhatt commented on the pull request: https://github.com/apache/storm/pull/339#issuecomment-67582859 @nathanmarz the re-emit can hit this issue in many pathological cases , bad kafka config, transient network failure causing storm batches to fail repeatedly while kafka queue with low retention getting truncated, very slow topology with really fast kafka producers with low retention rate so mostly around kafka config with lower retention rates. I have made the change you suggested during reemit we don't catch exception but let the spout fail.
