Yes to both of the questions. I was also able to reproduce the issue on a MBPro (also running 10.5). Limiting the speed on the 10.5 MacPro and seems to have done the trick so far. I spoke with a genius at the local Apple Store the other day and he said that he remembered hearing something about files missing when copied to a 10.3 server but that he thought it was a 10.6 client issue. Someone else mentioned that it may be the way that 10.3 stores metadata over AFP.
