I am also seeing similar behaviour with openvpn; however, restarting the daemon doesn't stop nss_wins entries from being added to syslog. Below are the syslog entries after restarting the openvpn daemon. It looks as through openvpn-server entries are correct, but openvpn-client items are changed to nss_wins.
