NGINX algumas vezes tem erro (Nenhum arquivo ou diretório)

Question

Depois de algum tempo meu servidor nginx terá um erro com relação a arquivos estáticos, estou usando o NGINX em um servidor que serve arquivos estáticos e como proxy para o aplicativo Django em outro servidor.

Eu copio os arquivos estáticos do servidor Django para o servidor NGINX e executo o comando ./manage.py collectstatic .
