BuddyPress.org

When BuddyPress is installed on a machine with nginx and PHP-FPM, then WP won’t run anymore.

This error comes up in the nginx error log:

recv() failed (104: Connection reset by peer) while reading response header from upstream, client: xxx, server: xxx, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "xxx"

I tried a lot, no success. Any clues?
