Stalled cache updating and upstream timeouts?


I get 2 errors into nginx logs, constantly:

  • stalled cache updating, error:0 while closing request AND
  • upstream timed out (110: Connection timed out) while reading response
    header from upstream

I use fastcgi as upstream, with next_upstream set to error only and
send_timeout at 60s.
Could you be kind and help me understand when these 2 errors occur?

Thank you.
