There is a fix in the upcoming 2.6.4 for the -z option of rsync when
transferring large files (those whose blocksize go past 64K).  If you
can, build either the 2.6.4pre3 release (listed on the web site) or the
latest nightly tar file (which has a couple extra minor fixes in it):

http://rsync.samba.org/ftp/rsync/nightly/rsync-HEAD-20050319-1628GMT.tar.gz

It is the sending side that needs to have this fixed version (if you
can't apply it to both sides).  I would appreciate knowing if that
fixes the problem for you.
