Just guessing...

Are you _doing_ the same thing in each case?  
That is, not, "did you type the same command",
but does rsync perform the exact same block transfers?

You use rsync to move changes from one machine to another,
are you moving the same changes?
Maybe there isn't much difference between the files on the linix machines.
