502

2010/09/19 14:52:07 [error] 1419#0: *10220 recv() failed
(104: Connection reset by peer) while reading response header from upstream,
client: [...], server: [...], request: "POST /[...] HTTP/1.1", upstream: 
"fastcgi://unix:/server/php-fpm.sock:", host: "[...]",
referrer: "[...]"

This is the error I'm receiving randomly. 95% of the time my setup works perfectly, but once in a while I'm getting 502 for 3-4 subsequent requests.

I'm using Unix socket between the server and the PHP process as you can see, also have set up FastCGI params (SCRIPT_FILENAME), etc. correctly.

What can I do about it to strengthen the connection between these services?

Thank you very much in advance.

GeoIP and Nginx

I have a nginx with geoip, but it is not working rightly. The issue is the next: Nginx are getting geodata from $_SERVER['REMOTE_ADDR'] instead of $_SERVER['HTTP_X_HAPROXY_IP'], which have the real client ip. So, the reported geodata belongs to my server ip instead of client ip. Does anybody where… >>> More
