Rahul,

I have the same problem and I think I, probably, know what's causing it. The bad thing is that I got it trying to solve another one and I don't know how to fix both :)

So, until today, my server sometimes issued 504 error. The error log reported "upstream timed out (110: Connection timed out) while reading response header from upstream" error. Trying to fix it, I played with various PHP-FPM timeouts. So, I increased pm.max_children from 5 to 10 and set request_terminate_timeout to 30s. Immediately after these changes had been  made, 504 error was gone, but now I receive 502 with the same diagnostics as yours: "Connection reset by peer".

Do you have request_terminate_timeout defined in your php-fpm.conf?

you have too many connections and FPM is not able to handle everything. You can play with backlog, max_client and timeouts.
