Kookka zookeeper continues to display information. Message "Received socket connection from /10.xxx.xxx.xxx"

Question

I worked on an existing Kafka, but some of them stopped responding to the "retention.ms" configuration. I installed a new copy of Kafka 0.8.2.1 and launched it. but he continues to show informational messages, such as: The IP address that he shows is the valid IP address on our network that creates messages on it. But even his car is turned off, he keeps showing him

Answer 1

Based on the comments, to make sure Kafka noticed that the car was no longer there, it was necessary to restart the machine, as well as Kafka.
