2011/11/14 14:02:24 [crit] 11819#0: *26 rename() "/var/www/0000000013"
to "/var/www/" failed (20: Not a directory) while reading upstream,
client: 111.222.333.444, server: www.test.com, request: "GET /
HTTP/1.1", upstream: "https://IIS:500/", host: "www.test.com"

Установка соединения с сайтом идет
очень долго, потом контент отдается за
пару секунд.
Можете подсказать какие есть ошибки в
конф файлах? И что можно еще подправить
для ускорения отклика.
