Hello

I am using Nginx with Circus. Circus is used with chaussette

Very rarely I am seeing 504 error

Nginx error log says

upstream timed out (110: Connection timed out) while reading response  
header  
from upstream, client: A.B.C.D, server: [servername.com](http://servername.com), request: “GET /  
HTTP/1.1”, upstream: “[http://127.0.0.1:8080/](http://127.0.0.1:8080/)”, host: “[servername.com](http://servername.com)”

The process listening on port 8080 are circusd and chaussettes. What  
could  
be the cause
