You are sending systemctl restart ntpd into the background and kill it the hard way. I understand you don't want to wait forever, but killing it instantly (while it restarts ntpd) could cause some "funny" behaviour. This behaviour might also be somewhat random/racy because the kill can happen at different states of the restart. Can you still reproduce the issue you described if you at least add a "sleep 5" before killing systemctl?
