The "Broken Pipe" and the "error in rsync protocol data stream" are
both aftermath of a previously occurring error.  The other errors all
mean that the sender received something invalid from the generator.
That could indicate either a bug in rsync or corruption in the network
connection.  You could dump the data that each side sends and receives
over the network using the "savetransfer" program that comes in
support/ of the rsync source package (
http://rsync.samba.org/ftp/rsync/rsync-2.6.9.tar.gz ) to determine
whether network corruption is occurring.
