Похоже проблема в post_action + fastcgi.
Вот тестовый конфиг, с которым проблема воспроизводится:


user ai;
worker_processes 1;

events {
worker_connections 1024;
}


http {
include mime.types;
default_type application/octet-stream;

sendfile off;
aio on;
output_buffers 1 256k;
tcp_nopush on;

keepalive_timeout 0;

gzip off;
charset off;

server {
listen 80;
server_name localhost;


location /upload.html {
alias /home/ai/up/test/form.html;
}

location / {
root /home/ai/filmes/dvd;
autoindex on;
post_action @ok;
}
location = /status {
stub_status on;
}
location @ok {
fastcgi_pass 127.0.0.1:9000;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME /home/ai/up/php/compl.php;
}
}
}

13 последовательных закачек дали

13 CLOSE_WAIT

Если убрать post_action, проблема не воспроизводится.
