nginx的错误日志：
/01/23 21:56:23 [error] 3473#0: *118756 upstream prematurely closed FastCGI stdout while reading response header from upstream, client: 150.242.228.234, server: , request: "GET /checkout/repurchase/?code_id=9e6a16&from=cart&machine_no=eus HTTP/1.1", upstream:
"fastcgi://unix:/tmp/php-cgi.sock:", host: "", referrer: "/checkout/myCart/?code_id=9e6ab74ae2f&machine_no=eus"
4台服务器都是这样的配置绑定hosts的时候只有其中一台报这种错误
nginx.conf主配置：
fastcgi_buffer_size 128k;
fastcgi_buffers 4 129k;
改为下面的参数后问题解决：
fastcgi_buffer_size 128k;
fastcgi_buffers 32 32k;
