Hello, I wonder if you are aware of some memory leak on kafka-clients 3.0.0. I'm having this issue reported here: https://github.com/spring-projects/spring-kafka/issues/2056
It is a Spring Boot 2.5.7 application that started failing when updated to Spring boot 2.6.1. This updated kafka-clients 2.7.1 to 3.0.0 and started causing the memory leak. Downgrading just the lib kafka-clients to 2.7.1 solves the issue. Any idea? Best regards, Willian Dallastella
