Trying to figure out why my LEB with APACHE2/PHP/OpenVPN-AS is using 92MB of RAM :s

Done:
apt-get remove bind9

Fortunately it is a 768MB RAM VPS, but I don't understand why it was using over 100MB of RAM with APACHE2 (default with the vanilla install) and OpenVPN AS installed. I subsequently installed PHP. which increased the RAM usage by a couple MB.

Anyway, "free -m" currently shows usage of 92MB RAM, but "ps aux" shows a ton of openvpn processes ("openvpn --errors-to-stderr --config stdin") and I'm not sure why they are all running. The VPN works.

Thoughts/suggestions about what to do to improve (reduce) RAM usage (short of getting rid of APACHE2 and replacing it with nginx, though I guess that's a possibility) and clean up the OpenVPN and related processes are welcome.
