eu encontrei a mesma pergunta, a solução é aplicar essas configurações ao proxy:
keepalive_requests 500;
proxy_http_version 1.1;
context: http, server, location
A versão 1.1 é recomendada para uso com conexões keepalive
Estou executando o nginx no Windows Server 2008 R2 e ele parece estar travando, ele também usa o php-cgi com ele e o php-cgi faz parte do problema. Após cerca de 30 segundos de estar na página php-cgi fecha e pára de funcionar, mas isso só faz com que ele falhou ao visitar apenas 1 página, com chamadas ajax .. parece ser as chamadas ajax causando o erro, e no erro nginx log eu tenho os seguintes erros abaixo

Eu também verifiquei meu arquivo de configuração do nginx, mas como sou novo no nginx, não consigo descobrir o que está errado e o que está certo com ele, colei-o abaixo.

Já visitei muitos sites sobre esse erro, mas ainda assim nenhum site finalmente me ajudou, também editei este arquivo do original do pacote nginx download.
Meu código ajax funciona perfeitamente no xampp e iis, mas não no nginx ...
