Resolution: Duplicate
> Kafka Connect Connection leak to Kafka Brokers when using dead letter queue
> ---------------------------------------------------------------------------
>
> Key: KAFKA-10045
> URL: https://issues.apache.org/jira/browse/KAFKA-10045
> Project: Kafka
> Issue Type: Bug
> Components: KafkaConnect
> Affects Versions: 2.1.1, 2.3.0, 2.4.1
> Reporter: rameshkrishnan muthusamy
> Priority: Major
>
> we are encountering a connection leak which accumulates over a period of time
> as the number of rebalances increase in Kafka Connect. The connection to the
> Kafka Broker for dead letter queue is never closed during rebalance. At the
> same time as part of rebalance a new connection is created for the dead
> letter queue kafka topic. This results in accumulation of open connections to
> Kafka Broker. This impacts the total no of connections and causes load on the
> kafka brokers over a period of time.
