调试模式下的Django Broken pipe

我在Nginx后面的远程服务器上安装了Django 1.3.

如果我使用apache+mod_wsgi运行Django，我可以查看Apache日志(log)文件中的错误.可以，但我想要控制台的.

如果我运行django自己的开发服务器，只有当DEBUG=False时，控制台中的stacktrace才会出错.在调试模式下，控制台输出

Exception happened during processing of request from (..., ...)
Traceback (most recent call last):
  File "/usr/local/python/lib/python2.7/SocketServer.py", line 284, in _handle_request_noblock
    self.process_request(request, client_address)

    self._sock.sendall(view[write_offset:write_offset+buffer_size])
error: [Errno 32] Broken pipe

我想知道为什么？为什么django只输出未命名的异常？为什么它依赖于调试变量.

当我没有访问请求对象的权限时，此错误主要发生在视图外部.所以我无法在中间件或使用日志(log)处理程序中捕获它.

更新.我注意到，如果我直接向Django服务器请求，我永远不会遇到管道破裂的情况.那么这个问题会不会在Nginx代理Django的时候发生呢？
