This output seems to indicate that a write system call issued by the
generator failed with EPERM (Operation not permitted).  I don't think
write ever fails with EPERM on Linux or BSD.  What operating system
are you using?

I would recommend stracing the client to see exactly what system call
is failing.  (Run sudo strace -o rsync.log -f rsync (arguments...), or
use the strace equivalent for your operating system.)  Also try
running rsync at a higher verbosity level (-vv or -vvv) to get more
