Спасибо всем большое... Добился определенных результатов.
1. На сервере кроме ОС работает ППО (оно иногда пишет небольшие объемы информации - в час по 50-100 мб.) Поставил iozone тестироваться вместе с ППО - через 2.5 часа сервер повис. Потом через сутки опять iozone был поставлен но без ППО сервер выдержал.
2. Начал эксперементировать: работает ППО и запускаю скрипт obsec - перезагрузка системы. Работает ППО - и запускаю скрипт updatedb - система зависает.
3. Вчера вообще пипец начался: операторы по sftp копируют файлы с сервера и он стабильно перегружается.
У меня подозрения на дисковую подсистему точнее драйверы для raid массива (aacraid).

В свое время на других объектах я собирал с этими железками и драйверами на ядрах 2.4.32 и 2.4.35 и все работало без проблем.
Очень жду совета. Сейчас ситуация очень критическая. Если будут советы по пересборке ядра либо вывода более подробной диагностической информации в случании падения - буду очень признателен.
