Cannot get existing message queue
This error can indicate that an earlier Juke_Box custom server has not cleaned up correctly, or is still active. The Juke_Box custom server cannot create a message queue or use an existing message queue.
Remove the file /tmp/juke_box_message_queue_<userid> and make sure that the userid that started the Juke_Box custom server has write access to the /tmp directory. Restart the Juke_Box custom server.
