  include vhosts/vhosts.conf;
}



vhosts文件：
server {
    listen 88;
    server_name  10.10.10.x;
    root /data/wwwroot;
    index index.html index.php;
    error_log  /data/logs/nginx/access_error.log;

    location / {
        proxy_set_header Host $host;
        proxy_next_upstream error timeout invalid_header http_500 http_502 http_504;

        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        #proxy_set_header http_x_forwarded_for $remote_addr;
        proxy_set_header REMOTE_ADDR $remote_addr;
       # proxy_set_header X-REAL-IP $remote_addr;

        proxy_pass  svn;
    }
}



当下载文件为74M时，总是报这个错误：
2015/06/18 18:14:42 [crit] 3955#0: *19 writev() "/opt/nginx-1.2.7/proxy_temp/0/01/0000000010" has written only 7168 of 8192 while reading upstream, client: 10.10.10.xx, server: 10.10.10.xx, request: "GET artifactoryxx HTTP/1.0", upstream: " 192.168.0.xxxx", host: "10.10.10.xx"

百度、雅虎、google镜像都查了一下，可惜没看到相似的答案，我觉得应该是fascgi或这是proxy的一些参数问题，但是真不清楚该怎么调整，请大家帮帮忙，谢谢了！

在vhosts里设置proxy_max_temp_file_size 0;
解决问题。
