Yes. By the way:

The "A2" there is not printed by any upstream version of rsync, so your
copy is definitely modified.

Run your rsync command with -vv verbosity and look for an output line
that begins with "opening connection using:", which will show the remote
shell command used to invoke the server. If that line contains
--drop-cache, blame the sending rsync. Otherwise, run the command
manually. If the same error occurs, the receiving machine is at fault
(maybe a badly designed ssh forced command).

You can use a package management tool such as aptitude or install from
one of the source tarballs at http://rsync.samba.org/ftp/rsync/src/ .
