Как вы можете видеть, в статусе подчиненного устройства ошибок не отображается, но файл master_log_file задерживается на 4 журнала, и положение подчиненного устройства не меняется. Мне интересно, если это ошибка БД, ошибка сети или другие ошибки. Мы уже пробовали mtr и telnet с портом 3306 и его работоспособностью.
