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?
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 ?
