VSS corrupts often. However, the latest version of the source it does well
with. What corrupts are the history records and the versions you pull out of
history and I have seen this first hand on many instances. The analyze tool
really is finding data that is lost, so VSS is a horrible tool to manage this
(hence the benefits of SVN).
I wonder if the error comes from ssphys.exe, as I thought when Perl programs
fail they give an "exception"-like print.
Also I noticed when you DESTROY (delete permanently), it doesn't actually
remove anything from VSS. vss2svn actually recovers that. Just an interesting
side note. You might need to convert and use filters to get just the data you
need.

Hi, I am attempting to migrate a modest project from VSS to SVN.
* Our VSS database DATA folder is approximately 40GB in size.

However, vss2svn.pl terminates with one of 2 errors:
1. file corrupted, cannot continue or
2. memory error: "The instruction at "0x28085bc1" referenced memory
at "0x000000004". The memory could not be "written"." (This
last error occurs during "STARTING CACHE FOR PhysicalAction")
Can you help me understand what's going on here and what I might do?
Also, can you explain why VSS has so many corruptions (reams and reams
from ANALYZE) and yet never corrupts the source? Our developers have
never reported any source corruption.
