Specifically, are you observing files that contain unexpected garbage, unexpected regions of ASCII 0, unexpected contents of another file, etc? If it's possible to narrow it down further, using hexdump, is it possible to determine whether corruption begins and ends on page of file block boundaries? Also, is it possible for you to test whether you can trigger the corruption solely through remote access via Samba, and not through the use of other local programs and applications on the file system?
