Nginx + Circus + chaussette


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
from upstream, client: A.B.C.D, server:, request: “GET /
HTTP/1.1”, upstream: “”, host: “

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