To get more information, please strace rsync (which is especially easy
because all of the processes are local) and enable -vvv verbosity level:

strace -f -o /tmp/rsync.log rsync -vvv -r --inplace --size-only --bwlimit=50 /home/shares/allusers/127 /mnt/s3

If this does not make the problem obvious, post the output and I will
take a look.
