How to get rid of /tmp/atop.d/atop.acct

You should never terminate atop by 'kill -9', because then it has no chance to stop process accounting; as a result the accounting file may consume a lot of disk space after a while!!!

Lets do this smoothly:

systemctl stop atopd
systemctl disable atopd

Check atop processes
ps auxfS |grep atop

Kill if any using 'kill -15'
kill -15 PID

Check for links and unlink if any:
ls /etc/systemd/system/ |grep atop

Remove atopd.service
