Generally speaking you should not be getting those message when
you are doing things on the live r/w filesystem, but you CAN get
those messages when you are messing around with snapshots, and
that includes running 'undo' on the live r/w filesystem.
In particular running undo can cause these messages to appear
because undo will try to use unofficial transaction ids (those
for which an official snapshot has not been made), and these
unofficial transaction ids can 'catch' the filesystem in the
middle of an operation that happened to be split between two
I'd rather not remove the warnings just yet, there are some
split transaction cases which aren't supposed to happen but
still do that I want to eventually track down and fix.
Access through official snapshots (found in /var/hammer) can
also cause the messages to appear sometimes if the snapshot
was taking while a file was in flux. It isn't supposed to
happen for official snapshots but it still does sometimes.
