You are writing to the same file in parallel. That will not work.

Try this:

parallel -j 8 rsync -aHAX --delete --log-file-format='%o %f %L %l %b
%i %t' --log-file ../testlog{#} {} ../ddir/ ::: $@

This will create a new file for each job. Or this:

parallel -j 8 rsync -aHAX --delete --log-file-format="'%o %f %L %l %b
%i %t'" --log-file /dev/stdout {} ../ddir/ ::: * > ../logfile
