title: Tuples failing at the spout, and seems they are not even reaching the Bolt
body: <p>I have a topology running for a few days now and it started failing tuples from last couple of days. From the logs it seems that the tuples are not reaching the bolts, attached is the Storm UI screenshot.
  I am ack'ing the tuples in <em>finally</em> in my code, so no case of un'acked tuples, and the timeout is set at 10sec, which is quite high than the time shown on the UI.</p>
  
  <p>Any Hints ?<a href="https://i.stack.imgur.com/ECaxl.png" rel="nofollow noreferrer">enter image description here</a></p>
