title: Repeated consumption of a previous successful consumption every 5 minutes for half an hour
body: <p>Spring boot Version : 2.5.0
  Spring Cloud Version ： 2020.0.3</p>
  <p>I used Spring-Cloud-stream-binder - Kafka and Spring-cloud-stream-binder - Kafka-Streams for kafka production and consumption in the project.</p>
  <p>I found in the log that several messages were repeatedly consumed, and they were under a group.</p>
  <p>This keeps happening once every 5 minutes, a total of 5 repetitions of consume, plus the initial consume, a total of 6 times, a total of half an hour.</p>
  <p>I configured the retry policy to be a maximum of 3 times and then sent to DLQ, but no error message was found.</p>
  <p>What is the cause of this, or is there any way to help find some clues.</p>
