Nginx error


We have a strange issue with our rails app deployed on a linux box with
a nginx in front and a mongrel cluster behind. frequently i am getting
error in
nginx log

2008/11/20 10:19:33 [error] 8558#0: *375433 upstream timed out (110:
Connection timed out) while reading response header from upstream,
client:, server:, request: “POST
/waphandler HTTP/1.1”, upstream:“”,
host: “

Maybe somebody here made similar experiences and could give us a hint.
That would be great!



Hi Joe,

It looks like your backend mongrel is taking too long to respond to
the request, try increasing the proxy_read_timeout
