Atualmente, estou sempre recebendo um 502 em uma consulta que meus usuários estão fazendo ... o que geralmente retorna 872 linhas e leva 2,07 para executar no MySQL. No entanto, está retornando muitas informações. (Cada linha contém muitas coisas). Alguma ideia?

Executando a pilha Django (tastypie Rest API), Nginx e uWSGI.

Configuração do servidor com NGINX

# the upstream component nginx needs to connect to
upstream django {
    server unix:///srv/www/poka/app/poka/nginx/poka.sock; # for a file socket
}

# configuration of the server
server {
    # the port your site will be served on
    listen  443;


    # the domain name it will serve for
    server_name xxxx; # substitute your machine's IP address or FQDN
    charset     utf-8;

    # max upload size
    client_max_body_size 750M;   # adjust to taste

    # Finally, send all non-media requests to the Django server.
    location / {
        uwsgi_pass  django;
        include     /srv/www/poka/app/poka/nginx/uwsgi_params; # the uwsgi_params file you installed
    }
}

Configuração UWSGI

# process-related settings
# master
master          = true
# maximum number of worker processes
processes   = 2
# the socket (use the full path to be safe
socket          = /srv/www/poka/app/poka/nginx/poka.sock
# ... with appropriate permissions - may be needed
chmod-socket    = 666
# clear environment on exit
vacuum          = true

pidfile = /tmp/project-master.pid # create a pidfile
harakiri = 120 # respawn processes taking more than 20 seconds
max-requests = 5000 # respawn processes after serving 5000 requests
daemonize = /var/log/uwsgi/poka.log # background the process & log
log-maxsize = 10000000
