WITNESS warning output from 6.0-BETA3

[Oliver Fromme]

Hi,

I get the following output under FreeBSD 6.0-BETA3 when
WITNESS is enabled.  It doesn't seem to cause any harm,
though.  I cvsupped this system to RELENG_6 a few days
ago.

I have no idea what is causing this output, whether 
should worry about it, or even whether this is the right
list to report or ask about it.  :-)

The output occurs when booting, right when the interface
(bfe0) is configured for the first time.  I have a small
self-made script in /etc/rc.d which configures bfe0
several times with different IP addresses and performs
a ping test in order to find out in which network the
notebook is located, then symlinks various files in /etc
depending on the result.  The below output happens when
that script is executed.

Best regards
   Oliver
