Sto eseguendo nginx e tornado su istanze c1.medium.Tornado, Nginx, Apache ab - apr_socket_recv: Connessione ripristinata dal peer (104)
Quando corro ab il sotto è la mia uscita. Nginx non funzionerà. Ho provato a modificare il file di configurazione per ninx senza alcun risultato. Se corro su una sola porta passando nginx e.g. `
http://127.0.0.1:8050/pixel?tt=ff`
quindi veloce. Vedi il fondo. Questo deve essere un problema di nginx, quindi come posso risolvere? Di seguito è riportato anche il file conf per nginx.

Questo dovrebbe fumare ma ancora non è così.
ho impostare le seguenti parmamerts
ulimit is at 100000

se corro ab dai passando nginx:
