Hi! It could be that your process time for that tuples is greater than topology.message.timeout.secs 30 seconds. In these case have a look at your bolts processing time or how fast you generate your data from spout that could not cope with your bolts. You can: 1. Increase your level your parallelism for your bolts. 2. Throttling the messages from the spouts by setting out topology.max.spout.pending Please have a look at these questions: http://stackoverflow.com/questions/32322682/apache-storm-what-happens-to-a-tuple-when-no-bolts-are-available-to-consume-it
