我们有一个Kafka Streams应用程序（2.0），它正在与kafka经纪人（1.1.0）进行通信。流应用程序无缘无故地正在重新处理整个日志-应用程序没有重新启动，没有重新平衡并且只是闲坐着-在某些情况下它正在处理消息，在其他情况下它正在等待接收消息（已处理邮件少于6小时）。我们已经进行了大量研究，并通过将offset-retention-minutes设置为1周来排除potential cause，这与我们保留邮件的时间相同。此外，这不是消费者组偏移量在积极处理消息时被重置的根本原因。
围绕事件发生的时间，代理日志中没有有趣的事情：

并且在应用程序日志中绝对没有什么（ememthing ）（即使日志级别设置为DEBUG）。
关于什么可能导致此问题的任何想法？

将Kafka代理升级到2.0.0解决了此问题。
