1、报错
docker内部ng

2、问题排查
根据上放问题是临时文件的缓冲区不够
修改NGINX配置

	proxy_buffer_size   32m;
	proxy_buffers       12 16m;
	proxy_busy_buffers_size   64m;
        fastcgi_connect_timeout 24h;
        fastcgi_send_timeout 24h;
        fastcgi_read_timeout 24h;

问题排查初期（第二天）：

1、每次下载执行到49.30G就无故断开，连续测试多次

secure_download?key=54d4e2deca0598059daa524255a9c685     [                                                                                                                  <=> ]  49.30G  4.57MB/s    in 3h 21m 

2、修改php配置
但是实际观察占用内存并不是很高

ini_set('memory_limit', '100G');

测试还是和第二天一样

问题排查初期（第三天）：

找到外部nginx配置，修改如下：

        client_header_buffer_size 20m;
	large_client_header_buffers 4 18m;
	client_max_body_size 100g;
	proxy_max_temp_file_size 1001024m;

晚上同时执行两个下载

浏览器和命令行，两个下载均已成功

总结：

问题报错与断开原因有两个
1、缓冲区的配置不够，配置如下

	proxy_buffer_size   32m;
	proxy_buffers       12 16m;
	proxy_busy_buffers_size   64m;

2、固定下载到49.30G断开，配置如下

	client_max_body_size 100g;
	proxy_max_temp_file_size 1001024m;
