You should be aware that there are known issues with UniVerse 10.1.0
through to 10.1.6 (effectively the same version of UniVerse, but for
different platforms) that can cause data loss / corruption when DYNAMIC
files are used. These releases should be avoided for this reason alone,
and have been superseded.
HTH
The word I got was that the first release that had the "new & improved"
fixtool (the one that based on my tests not only works but even
reclaims orphaned buffers) is UV 10.1.2.
Note that is only the command line fixtool. The one in the GUI is a
different critter, and in my experience, should be avoided.
