Bug Description

Rossella asked me about this yesterday [1]. A brief discussion in the DVR meeting this morning [2] seems to indicate it is not a serious problem. But, I thought I'd submit this bug as a place to land for others who see this warning. Hopefully at some point we can get it cleaned up.

Here is the warning line from the log snippet in the pastebin [1].

I'm not sure that the presence of a warning in the logs is a real bug. This one has been around for well over a year and hasn't been linked to any failure. Should we just close it?

I spent a little time in logstash trying to correlated this with something bad. I couldn't.

If it isn't bad, should we lower the statement from WARNING to DEBUG so that it doesn't pollute operator logs?

    Lower l2pop "isn't bound to any segement" log to debug

    Per the discussion in bug 1362242, the log statement doesn't
    appear to be associated with anything bad happening. Therefore,
    this patch lowers the log level from WARNING to DEBUG to avoid
    polluting operator's logs.
