nginx Errno 32：有特定请求的断开的pipe道

我有一个NGINX /瓶/docker服务器使用： https ： //github.com/tiangolo/uwsgi-nginx-flask-docker ，它适用于运行小而不经常的请求。 但是，如果我尝试了一些大的请求，涉及每个从amazon s3下载约5mb的数据（可以说，一次10）。 我得到这个错误：

Exception in thread Thread-1: Traceback (most recent call last): File "/usr/local/lib/python2.7/threading.py", line 801, in __bootstrap_inner self.run() File "/usr/local/lib/python2.7/threading.py", line 754, in run self.__target(*self.__args, **self.__kwargs) File "/usr/local/lib/python2.7/site-packages/werkzeug/serving.py", line 659, in inner srv.serve_forever() File "/usr/local/lib/python2.7/site-packages/werkzeug/serving.py", line 499, in serve_forever HTTPServer.serve_forever(self) File "/usr/local/lib/python2.7/SocketServer.py", line 233, in serve_forever self._handle_request_noblock() File "/usr/local/lib/python2.7/SocketServer.py", line 292, in _handle_request_noblock self.handle_error(request, client_address) File "/usr/local/lib/python2.7/SocketServer.py", line 290, in _handle_request_noblock self.process_request(request, client_address) File "/usr/local/lib/python2.7/SocketServer.py", line 318, in process_request self.finish_request(request, client_address) File "/usr/local/lib/python2.7/SocketServer.py", line 331, in finish_request self.RequestHandlerClass(request, client_address, self) File "/usr/local/lib/python2.7/SocketServer.py", line 652, in __init__ self.handle() File "/usr/local/lib/python2.7/site-packages/werkzeug/serving.py", line 216, in handle rv = BaseHTTPRequestHandler.handle(self) File "/usr/local/lib/python2.7/BaseHTTPServer.py", line 340, in handle self.handle_one_request() File "/usr/local/lib/python2.7/site-packages/werkzeug/serving.py", line 251, in handle_one_request return self.run_wsgi() File "/usr/local/lib/python2.7/site-packages/werkzeug/serving.py", line 193, in run_wsgi execute(self.server.app) File "/usr/local/lib/python2.7/site-packages/werkzeug/serving.py", line 184, in execute write(data) File "/usr/local/lib/python2.7/site-packages/werkzeug/serving.py", line 165, in write self.wfile.write(data) IOError: [Errno 32] Broken pipe 

我已经尝试将更多的进程和线程添加到nginx / wsgi。 我的uwsgi.ini如下所示：

 [uwsgi] module = main callable = application processes = 8 threads = 2 

和我的nginx.conf看起来像这样：

 server { location / { try_files $uri @app; } location @app { include uwsgi_params; uwsgi_pass unix:///tmp/uwsgi.sock; } location /static { alias /app/static; } } 

有谁知道可能是什么原因造成的？
