1063	wrong status variable	AleksKayunov@…		"We use nginx+uwsgi stack and see many errors like:


{{{
Aug 30 00:00:55 imfmce-va-81-2 uwsgi: Tue Aug 30 00:00:55 2016 - SIGPIPE: writing to a closed pipe/socket/fd (probably the client disconnected) on request /provisioning/user/f205970b-6a9f-42b5-830f-c2bec9967b32 (ip 10.216.153.254) !!!
}}}


I understand that error occurs when client close connection before reading response or by uwsgi_read_timeout, but I don't understand why in access log I cann't see any error, nginx just log 200 OK:


{{{

}}}

We use next format log line:


{{{
log_format ss_log_format ""active\t[ \$pid ]\t\$remote_addr\t\$http_user_agent\t\$upstream_http_x_user_identity\t\$http_x_client_id\t\$http_x_request_id\t\$ssl_cipher\t\$request_method\t\$uri\t\$args\t\$upstream_http_x_durations\t\$status\t\$http_x_error_code\t\$connection_requests\t\$request_completion\t\$content_length\t\$request_length\t\$body_bytes_sent\t\$bytes_sent"";
}}}


I would like you to understand that, we don't need to fix this error, we just need have right access logs."	defect	closed	minor		nginx-core	1.8.x	invalid	status variable uwsgi		Linux dev0fmall-xxx-1 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt25-2+deb8u3 (2016-07-02) x86_64 GNU/Linux	"nginx version: nginx/1.8.1
