This is the following Unix error:

  34 ERANGE Numerical result out of range.  A numerical result of
            the function was too large to fit in the available space
            (perhaps exceeded precision).

Fingerprint.subfile is correctly using LargeFile.seek_in.  It also
performs some reads.  I dont see why this would result in this
error...


The function is called for fingerprinting resource forks in
AppleDouble files.  You can check this by using the "-debug osx"
option.

The only other place it is used is for fingerprinting a file that was
partially copied, to make sure that the prefix was correctly
transferred.


But maybe you should check your filesystem first...
