Hi Rainie, in general buffer pools being destroyed usually mean that some other exception occurred that caused the task to fail and in the process of failure handling the operator-related network buffer is destroyed. That causes the "java.lang.RuntimeException: Buffer pool is destroyed." in your case. It looks like you had some timeout problem while fetching data from a Kafka topic.
