comm: nginx Tainted: G

Это может означать, что у вас проблемы:

1. С буквой "э"
2. С ядром, собранным дебиан
3. С сетевой картой и/или её драйвером
4. С модулем памяти
5-100. Дофига с чем

Но скорее всего либо не хватает памяти либо nginx читает файло с
сетевого диска, а не с локального. Не претендую на истину ни в какой
инстанции.
