Dear all：
          flink version is 1.12.4，kafka version is 1.1.1。topology is very simple ，source-->flatmap--->sink ，enable checkpoint，job will fail after a few hours 。 the error message is 


Caused by: org.apache.flink.streaming.connectors.kafka.FlinkKafkaException: Failed to send data to Kafka: The broker received an out of order sequence number.
