Уважаемые ГУРУ, прошу помочь с проблемой. Сразу прошу сильно не пинать, пишу впервые сюда.
Проблема: Сервер самопроизвольно перезагружается без каких-либо записей в логах.
Железо: HP ProLiant  DL380G4
Ось: FreeBSD 7.1
Сервисы: apache, mysql (собран с поддержкой больших таблиц), nagios. Каждую ночь выгребаются данные из оракла и складываются в мускул
