Добрый день, достался по наследству сервер с битрикс. После переноса на другой сервер - выяснилось что mysql раз в день сьедает все 32ГБ памяти, свап и падает. После перезагрузки ситуация повторяется.
Полез смотреть в настройки mysql - но тут я профан. На мой взгляд в настройках сумбур, и явно что то не верно.
Что поправить чтобы память не улетала в небеса?
