У меня при очередном зависании сайтв на главной показало вот такие вот ошыбки

MySQL ERROR [select]: SELECT day(from_unixtime(postdate)) as day, count(id) as count FROM 2z_news WHERE approve = '1' AND postdate >= unix_timestamp('2013-02-01 00:00:00') AND postdate < unix_timestamp(date_add('2013-02-01 00:00:00', interval 1 month)) group by to_days(from_unixtime(postdate))
(2006): MySQL server has gone away

MySQL ERROR [record]: select ads_blok from 2z_ads_pro where id='14'

MySQL ERROR [query]: insert into 2z_load (dt, hit_core, hit_plugin, hit_ppage, exec_core, exec_plugin, exec_ppage) values ('2013-02-20 22:00:00', 1, 0 , 0, 30.77, 0, 0) on duplicate key update hit_core = hit_core + 1, exec_core = exec_core + 30.77
(2006): MySQL server has gone away

что они значат?

Это значит, что нужно увеличивать max_allowed_packet или оптимизировать запросы.

infinity237, а не подкажеш где увиличивается max_allowed_packet?

infinity237 · 2013-02-21 01:45:15

В etc/my.cnf
После перезагрузить mysql.

infinity237, я нашел этот файл в /etc/mysql/my.cnf

такое содержание

та в двух местах есть max_allowed_packet = 16M, менять надо у двух местах? на какое посоветуешь, надо ли еще чтото менять?

Для начала я бы поставил 24M.
