Hi, I was wondering about possible causes for the following log message: 2014-04-02 05:14:02 <TRACE> ospf1: Changing state of iface vlan0251 from ptp to down No other log messages prior to this one currently. I did enable debug logging hoping it would shed some more light on the issue. But I don't know when it'll happen again. This is bird 1.3.8 running in a vSphere VM, so there's plenty of areas where network issues could arise. Regards, Ruben Laban
