Hi.

I have set up nginx as load balancer and i seems to get this in the error.log

[quote][error] 7098#0: *85123 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 11.11.11.11, server: myserver.com, request: "GET /json/?callback=json166511 HTTP/1.1", upstream: "http://myip-one:80/json/?callback=jsonp166511", host: "server.sookachat.com", referrer: "http://myserver.com/docs.html"[/quote]

I've tried the solutions in this forum but so far none worked. Can anyone help?

My nginx version: 0.8.52

my nginx.conf and default.conf
