Additional corrections: there is a natural race between closing connection to cluster in case of applying error and finishing the IST and sometimes IST finishes and tries to send JOIN message over a closed connection. This does not affect the correctness of the test or node behavior. Added error message suppression. Signed-off-by: Julius Goryavsky <julius.goryavsky@mariadb.com>
