The files will be owned by the (AFS) user that created them. Only an AFS
administrator can change the owner of a file. As long as you are not
running rsync as root, it should not attempt to preserve owners, so this
shouldn't be a problem.
I use both rsync and unison with AFS on a fairly regular basis, and both
tools behave exactly as expected.

OK, so something sent SIGINT or SIGUSR1 to one of your rsync processes,
which caused it to exit, confusing the thing at the other end of the pipe.
You should figure out what that is. This sounds like a problem with rsync,
