The OpenVMS editors typically create a file that is in a variable text
format. When SAMBA 2.0.6 transfers it, it automatically translates it
as appear to be a STREAM_LF file.

SAMBA 2.0.6 will attempt to write a file in the same format as the
original. Obviously there is a bug here somewhere. Samba is expecting
the C RTL to translate the records.

Try FORMAT of STREAM_CR.
Many PC utilities are use what OpenVMS terms STREAM_CR format for it's
UNIX uses what OpenVMS terms STREAM_LF format for it's files.
Using SET FILE/ATTR on a corrupted file to change it's attributes to be
a STREAM_CR may also rescue it's contents. Or it may not.
