Добрый день.

Как можно пофиксить?

Добрый день, на какой ОС запускаете? Какая версия MySQL?

SirMaxBlack · Answer 2 · Mon May 08 2023 00:07:15 GMT+0800 (China Standard Time)

Система: "Debian GNU/Linux 11 (bullseye)"

Мария: Your MariaDB connection id is 131040
Server version: 10.5.15-MariaDB-0+deb11u1 Debian 11

Непонятная ошибка (на debian 10 все нормально работает, 11 нет под руками чтобы проверить), запустите пожалуйста скрипт так
bash -x ./mysql-stat.sh
и пришлите весь вывод
