Edoardo Comar commented on KAFKA-16369:
---------------------------------------

server logs as broker only (zk mode) and broker/controller (kraft mode) when port 9092 is already bound

[^server.log][^kraft-server.log]

> When in Zookeeper mode, if a port the broker should listen to is already bound
> the KafkaException: Socket server failed to bind to localhost:9092: Address already in use.
> is thrown but the Broker continues to startup .
> It correctly shuts down when in KRaft mode.
> Easy to reproduce when in Zookeper mode with server.config set to listen to localhost only
> {color:#000000}listeners={color}{color:#a31515}PLAINTEXT://localhost:9092{color}
