CakePHP 1.3.3 and Nginx + FastCGI

Question

I've used the following Nginx CakePHP Vhost template for a while now, with success.

But now it seems that the newer version of CakePHP (1.3.3) doesn't work at all.

It might be that it has nothing to do with the above Vhost template and that it is an error with FastCGI or Nginx.

The error is the following:

I get a 502 error and this line is written in my /var/log/sitexyz.error.log:

2010/09/16 15:58:59 [error] 2792#0: *81 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 172.20.0.2, server: testserver.xyz, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "testserver.xyz"

Any thoughts?
