Good morning! I used kafka for queue messaging and it worked good but then I have played with enabling SSL on Windows 7 by link https://github.com/edenhill/librdkafka/wiki/Using-SSL-with-librdkafka, changed server.properties file, then got error on starting kafka: The requested operation cannot be performed on a file with a user-mapped section open. I rollbacked changes but error is still here. I even unpack new version of kafka in another folder, but still have the same issue.
Could you please help with it? Thank you very much. Pavel
