用flask写了个后台，直接用ip访问没有问题，但是用nginx反向代理多刷新几次页面就挂了。

return flask.render_template('index.html', ip=ip, url=url, total=total)
--------------------- update -------------------
直接用命令行python run.py启动没有问题
启用supervisor重定向标准输出到日志文件，请求频繁就会爆Broken Pipe错误
不论是否使用supervisor，用nginx反向代理请求频繁都会报错
所以我个人觉得是写日志文件的原因，在supervisor和nginx里如何配置可以规避这个问题呢？

你用的是flask自带的内置的测试用的http server，不支持并发。你请求频率过高，可能就会出现你所说的错误。
