Здравствуйте.

Поставил MYSQL, сайт работает на отлично, но, пройдя некоторое время база отключается. Бывает через 5 минут, а бывает даже через час. В чем может быть проблема?

MYSQL Version 5.1
Debian 6

Ошибка:

MySQL Error! 
------------------------

The Error returned was:

Помогите пожалуйста!

Верните стандартный конфиг MySQL и больше к нему не прикасайтесь.

Вот я тоже об этом подумал, что проблема в моем конфиге. Знать бы какая переменная все испортила  ag

Навскидку max_connections, max_connect_errors, join_buffer_size, read_buffer_size, read_rnd_buffer_size, sort_buffer_size, myisam_sort_buffer_size сильно завышены. Проще вернуть дефолтный конфиг, чем с этим возиться.

Жаль, но даже возврат дефолтного конфига не помогло. Почему?!

Хотя нет, вроде перезагрузил mysql, пока не вылетает. Посмотрим еще.
