Comment 6 for bug 516016

Problem also occurs on a 10.04.1 machine, where OpenVPN is supposed to be listening to connections coming in on a bridged interface (ultimately to place client sessions on that same interface).

Looking at that log segment, we can also see that ntpd has failed in the same way, so this is not an openvpn-specific problem
