Hi,
I was trying to upgrade my bird instance from v1.6.0 to v1.6.3 today.
Unfortunately immediately after start the bird started generating these
messages
2016-12-30 12:02:35 <INFO> Started

It's a full BGP IPv4 instance with just three interfaces. Tested on
linux kernels 4.4 or 4.8. Package is from cznic deb repository.
I can see the warning log line was added at Dec 20 2016, which ended up
in 1.6.3 release. Hence this was happening probably even before the
upgrade, but it was not visible.
So the question is simple. Does it means there is something terribly
wrong with my machine, or the high rate of this warning is expected?
Cheers
Michal
