Hi Dave, No, there shouldn't be anything in recent patches that can explain or fix this. I have a few questions: 1) What filesystem are you using on the server, and does that filesystem support high resolution timestamps? 2) Does the file length on the server match the reported erroneous file length on the client? 3) Do the mtime and ctime on the erroneous file match on the client and server?
