The matlab primitives 'load' and 'save' for accessing files would return errors like "error using load", "File may be corrupt", "unable to read", etc.  This also happened only when matlab was compressing the data file.  We were able to create a test case in matlab that created-wrote-read a file that would fail within a few iterations to work on this.

SMB2 has *NO* unix extensions currently...

Can you log a bug at bugzilla.samba.org
and upload some packet traces captured
with wireshark on port 445 showing the
problem ?
