So I did:
sh-5.0$ rsync -vvv --rsh=ssh --rsync-path=/usr/bin/rsync --numeric-ids --perms
--owner --group -D --links --hard-links --times --block-size=2048 --recursive
--one-file-system root@localhost:/var/lib/lxc /mnt/testrsync/
>/mnt/testrsync/stdout2.txt 2>/mnt/testrsync/stderr2.txt
sh-5.0$ echo $?
13
With the following results:
— begin stderr2.txt
rsync error: errors with program diagnostics (code 13) at log.c(245)
[receiver=3.2.3]
rsync: [generator] write error: Broken pipe (32)
— end stderr2.txt
— tail of stdout2.txt

Note I drastically shortened the content of the write(1, …) commands in the
same style they were shortened anyway; guess it is just file content.
I must admit that I’m none the wiser. The sending half obviously wanted to
write exactly the same diagnostic as the receiving half did ("errors with
program diagnostics (code 13)“) - but couldn’t because the communication pipe
was already broken. It looks as if the sending side was unexpectedly struck
from the receiving side closing the connection. Whereas the receiving side
doesn’t seem to give any indication of what is going wrong apart from that
somewhat generic message.
Hope this helps anyway!
Best regards,
Andreas.
