recv() failed (104: Connection reset by peer) while reading response header from

如果是自己用c++写的server，这个错误信息一般表示客户端主动断开了连接

 

nginx中也有类似的错误信息，具体如下

原文：http://blog.csdn.net/kevin6216/article/details/8669293

Nginx + uWSGI，get请求头过大，报502 Bad Gateway

如下，较大的get请求：

NGINX中的error.log日志记录，表现为，类似：

recv() failed (104: Connection reset by peer) while reading response header from upstream

 

 

 

解决办法，在uwsgi中添加参数：

/usr/local/sbin/uwsgi -s 127.0.0.1:1182 -M -R 200 -p 4 --virtualenv="/usr/local/python-env/test-env" --env "DJANGO_SETTINGS_MODULE=settings" -w "django.core.handlers.wsgi:WSGIHandler()" --post-buffering32768

--buffer-size 32768
