我build立一个Joomla网站使用docman进行文件pipe理/下载。 该网站build立在运行Nginx 1.4.2和PHP5（FPM）的Ubuntu 14.04服务器上。
我遇到的问题是文件下载不一致（在大小方面）。 例如，我从网站下载了一个PDF文件6次，结果如下：
对于这个testing，完整的文件正确下载了6次。 其他4次文件不完整。
我的nginx.conf看起来像这样
user www-data; worker_processes 1; error_log logs/error.log; worker_rlimit_nofile 8192; events { worker_connections 4096; } http { include /etc/nginx/conf/mime.types; include /etc/nginx/proxy.conf; include /etc/nginx/fastcgi.conf; index index.php app.php index.html index.htm; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] $status ' '"$request" $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log logs/access.log main; sendfile on; tcp_nopush on; server_names_hash_bucket_size 128; # this seems to be required for some vhosts keepalive_timeout 0; #GZIP# gzip on; gzip_http_version 1.1; gzip_comp_level 6; gzip_min_length 1100; gzip_buffers 4 8k; gzip_types text/plain application/xhtml+xml text/css application/xml application/xml+rss text/javascript application/javascript application/x-javascript gzip_proxied any; gzip_disable "MSIE [1-6]\."; include /etc/nginx/sites-enabled/*; 网站configuration如下所示：

基于日志文件解决的问题…
我更改了/ var / lib / nginx / fastcgi文件夹的权限，它工作。
chown -R www-data /var/lib/nginx/fastcgi
