Hi, we are using Spring boot with *spring-kafka* and when updating to Spring Boot 2.6+ we have memory leak in the kafka producer as it comes with *kafka-cients 3.0.0*.
After testing, using Spring Boot 2.6 and just *downgrading kafka-clients to 2.7.1*, the *memory leak stopped*. Here are more details: https://github.com/spring-projects/spring-kafka/issues/2056 Are you aware about this issue? Best regards, Willian Dallastella
