http://pastebin.com/LcJzzYQd - вот кусок кода, за сегодня, как я понял ошибка в БД, что можно предпринять, сервер падает несколько раз в день, а иногда работает на протяжении нескольких дней без падения, что то не так с настройками или все таки надо смотреть на базы?

Есть выделенный сервер с ISPmanager панелью, система CentOs 6? железо : CPU: Intel Atom D2700 2.13GHz 1Mb (2 ядра / 4 потоков) RAM: 4 GB DDR3 HDD: 500 Gb

Время от времени падает, возможно проблемы с памятью, перед падением в логах такое, последние строки лог файла:
