Rsync Error 3.0.6 [solved]

Hello,

I use procedures for backup with rsync. The data where “pulled” by the backup server.

Sender: Now CentOS 5.9, receiver CentOS 6 updated on July 3.

Up to yesterday it run OK.

Today morning I made yum update to sender CentOS 5

Now I get

rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(600)
[receiver=3.0.6]

yum.log says, rsync was not updated this morning.

Both Versions 3.0.6

The command is like:

/usr/bin/rsync –password-file=/etc/rsync.server –delete –backup
–backup-dir=/backup1 –bwlimit=5000 -rtz user@server::dir/ /backup/

any idea?
