OpenVPN server instances

[nug]

If I do a

ps | grep openvpn

I get the following result:

1770 admin 3536 S /etc/openvpn/vpnserver1 --cd /etc/openvpn/server1 --config config.ovpn
1774 admin 3496 S /etc/openvpn/vpnserver1 --cd /etc/openvpn/server1 --config config.ovpn
3351 admin 3812 R /etc/openvpn/vpnclient1 --cd /etc/openvpn/client1 --config config.ovpn

Is it normal to have two instances/processes for the openvpn server?
