Since rsync expects a lot from the filesystem, it occasionally runs into
incompatibilities with network filesystems. You will probably have
better luck running rsync on the actual destination machine (either over
ssh or as a daemon), if possible.

Please reduce the set of source files to the minimum with which you can
reproduce the errors, run rsync under "strace -f", and send the output.
That will show the interaction between rsync and the filesystem leading
up to the errors and help me determine which is at fault.
