             Summary: Improve error messages verbosity
                 Key: KAFKA-7375
                 URL: https://issues.apache.org/jira/browse/KAFKA-7375
             Project: Kafka
          Issue Type: Task
    Affects Versions: 1.1.1
            Reporter: Seweryn Habdank-Wojewodzki


Dears,

Very often when clients are trying to connect we see in Kafka logs:

{code}
“org.apache.kafka.common.network.SslTransportLayer  - Failed to send SSL Close 
message“
{code}

The problem here is following: there is no word who? No IP, no client addres, 
nothing.

Would be great to have in all error or warning reports like this one, very 
precize information which client has a problem, to be able to solve it. When 
the number of clients is more than 10, this message is completely useless and 
when there are even more clients it really spams logs.

Thanks in advance for help.
