rest - Fixing broken pipe error in uWSGI with Python

Question

While hitting a REST resource (my_resource) in Python, the uWSGI server is throwing the following error in its log:

SIGPIPE: writing to a closed pipe/socket/fd (probably the client disconnected) on request my_resource (ip <my_ip>) !!!
uwsgi_response_write_body_do(): Broken pipe [core/writer.c line 164]
IOError: write error

It seems to be related to a timeout (the client disconnected before the request could finish processing).

What sort of timeout is this and how can it be fixed?

Answer 1

it depends on your frontend server. For example nginx has the uwsgi_read_timeout parameter. (generally set to 60 seconds). The uWSGI http router as the --http-timeout default to 60 seconds and so on. As you are talking about a rest api i am quite doubtful it requires more than 60 seconds to generate a response, are you sure you do not have some wrong response header triggering a connection close by the frontend webserver ?
