I have a client copying server data for backup using rsync over ssh

rsync --numeric-ids --partial -az --rsh=ssh --del --compress root@1.2.3.4:/home_server_path/ /path_to_local_backup/

the problem:
if server rsync is compiled from rsync-3.0.9-12.fc19.src.rpm
then any client rsync version works fine (rsync-3.0.9, rsync-3.1.0-2 , rsync-3.1pre1)

If server rsync is compiled from rsync-3.1.0-2.fc21.src.rpm
then no client rsync works to completion.
Typically transfer starts, go for 1-2 hours, then fails with error message like this:

--------- client 3.1.0pre1 errors----------
