У меня есть производственная база данных объемом 2,5 ГБ, которую я экспортировал с использованием mysqldump.
Я попытался импортировать этот файл .dump на другой сервер, запустив
mysql -uroot moodle
он работает в течение нескольких секунд и застревает. Когда я проверил mysql_error.log

В рабочей базе данных работает нормально, в чем будет проблема?
