This is the error I am facing when I start confluent kafka. Ksql Db was starting absolutely fine up until now when I ran into this issue. I am aware that port on to which ksqldb starts shouldn’t be occupied by any other process, so that’s not an issue.

Anyway, here is the latest entry of the ksql log file.
