Hi there,
I am using nginx as a reverse proxy on a Debian Linux.

The nginx is running on server A, and apache is running on server B.
Server A is a pure proxy, server B is the real web server.

In most of time, nginx works well.
But the HTTP port (80) will stop accepting new connection sometimes.
When it happened, I tried to telnet port 80 from the server by "telnet localhost 80", the telnet was just keeping trying but cannot make socket connection.

I checked the total HTTP connections by "netstat -an | grep 80 | wc -l", the number was always less than 2000.

I am using nginx package from Debian Linux, the package was installed by apt-get.
I added "ulimit -n 65535" into /etc/init.d/nginx to turned the "open files" limitation.

The problem is not resolved yet. Can anyone help?

Thanks.
