[Zope-DB] CorruptedDataError when migrating Data.fs

[David Durham, Jr.]

Hi all,

I've got what should be 2 identical repoze.plone (zope+plone+wsgi)
instances running on 2 centos machines.  The first machine I installed
and setup.  The second machine was setup by another admin based on my
instructions (so it's possible there's something different, but they
appear identical to me.)

What I'm doing is migrating a plone 3.1 site from one machine to the
other by way of a filesystem copy of Data.fs and Products directory.
I come across the following error in zeo.log:

Anyone know what the cause for this might be?  The 2 Data.fs files on
the different machines have the same size.
