# FlinkKafkaConsumer issue with stop with savepoint
<a name="troubleshooting-FlinkKafkaConsumer"></a>

When using the legacy FlinkKafkaConsumer there is a possibility your application may get stuck in UPDATING, STOPPING or SCALING, if you have system snapshots enabled. There is no published fix available for this [issue](https://issues.apache.org/jira/browse/FLINK-28758), therefore we recommend you upgrade to the new [KafkaSource](https://nightlies.apache.org/flink/flink-docs-master/docs/connectors/datastream/kafka/#kafka-source) to mitigate this issue. 

If you are using the `FlinkKafkaConsumer` with snapshots enabled, there is a possibility when the Flink job processes a stop with savepoint API request, the `FlinkKafkaConsumer` can fail with a runtime error reporting a `ClosedException`. Under these conditions the Flink application becomes stuck, manifesting as Failed Checkpoints.
