It may be that your network hardware is flaky (switch, cable, card) — or could also be some bug in the driver or network-manager/dhcp.</div><div class=""><br class=""></div><div class="">A quick google suggests people having problems with a all of the above causing similar log messages, so opening a bug on launchpad with a full copy of the log output from syslog is probably your best course of action. Feel free to also post a copy of syslog here so I can review the exact series of events.</div><div class=""><br class=""></div><div class="">Regards,</div><div class="">Trent</div><div class=""><br class=""></div><div class=""><div><blockquote type="cite" class=""><div class="">On 12 Jun 2015, at 6:53 AM, Jeremy Greene <<a href="mailto:jeremy@zeevee.com" class="">jeremy@ZeeVee.Com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""> <meta http-equiv="Content-Type" content="text/html; charset=Windows-1252" class=""> <div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""> <div class=""><span style="font-family: Calibri, sans-serif; font-size: 14px; line-height: 15.9899997711182px; widows: 1;" class="">- Ubuntu 14.04 LTS loaded on an Intel NUC </span><br style="line-height: 15.9899997711182px; widows: 1;" class=""> <span style="font-family: Calibri, sans-serif; font-size: 14px; line-height: 15.9899997711182px; widows: 1;" class="">- Unplug eth0 from network with dhcp server </span><br style="line-height: 15.9899997711182px; widows: 1;" class=""> <span style="font-family: Calibri, sans-serif; font-size: 14px; line-height: 15.9899997711182px; widows: 1;" class="">- As expected, dhcp client withdraws its address and a few seconds later, avahi-autoipd will generate a 169 address.
