It wouldn't surprise me if this is a completely unrelated problem.
Any chance that the python your using to test doesn't have large file
support?  Check by importing test.test_largefile.

We recently discovered that there's a bad interaction between ZODB and
Python without large file support running on a platform that supports
large files.  In this specific configuration, os.path.exists() returns
false for files >2 GB and ZODB creates a new Data.fs.
