Доброй ночи,
Обновил до 0.8.53, в журнале получил следующее:

2010/10/24 01:12:34 [alert] 27808#0: *50819 writev() failed (14: Bad  
address), client: x.x.x.x, server: sub.domain.ru, request: "GET  
/data/28.csv HTTP/1.1", host: "sub.domain.ru"

Конфиг:
…
location ~* ^/data/([0-9]+)\.csv$ {
error_page 404 =200 http://sub.domain.ru/stat_data.php?id=$1;
}

Сделал отладочный лог.
