Действительно, ошибка возникает когда мало памяти:

total used free shared buffers cached
Mem: 4049 3867 182 0 399
2359
-/+ buffers/cache: 1108 2941
Swap: 3820 0 3819

Но почему не используется оставшиеся 182 мегабайта, почему не
используется свап?

Используется нестандартная модификация, которая делает clone перед тем
как начать отдавать файл (а-ля userprivs), не самый лучший вариант, но
это единственный сервер где такая ошибка.
