> The [KPL 
> version|https://github.com/apache/flink/blob/release-1.9/flink-connectors/flink-connector-kinesis/pom.xml#L38]
>  (0.12.9) used by flink-connector-kinesis in the affected Flink versions has 
> a thread leak bug that causes applications to run out of memory after 
> frequent restarts:
> KPL Issue - [https://github.com/awslabs/amazon-kinesis-producer/issues/224]
> Fix - [https://github.com/awslabs/amazon-kinesis-producer/pull/225/files]
> Upgrading KPL to 0.12.10 or higher is necessary to avoid this issue. The
