Have no idea what caused it as I found the message on my console
somewhat after the fact. The system had been up over 24 hours and
is still running. System still seems 'fine' (been up 3 days now),
so you can treat this as a "data point".

Are you perhaps an XFS user?

   Funny you should mention that...  yes.  However, there were no
other messages that seem to indicate that the message had anything
to do with XFS.  Nice shot in the dark.
