@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.
