The first command is of the form that rsync uses to invoke itself over
a remote shell.  Are you running this command yourself?  If so, why?
Is this instead of or in addition to rsync invoking itself on the
"client" as a result of the second command?  If you explain your setup
a bit more, I will have a better idea of why it isn't working.
