That's what I though, but I've got no nginx-php connections in ESTABLISHED mode when a client-nginx connection goes to CLOSE_WAIT.
This is what I get now on a netstat -nap:

11 client-nginx connections in CLOSE_WAIT, no nginx-php connections. Unless they're the last four unix domain sockets connections, but I've configured nginx to use 127.0.0.1:9000 as the fcgi server.
How can I debug what these CLOSE_WAIT connections were doing, which request were they serving? Anything I can activate on the logs or on nginx-status, a la Apache's extended server-status?
Thanks
