..on installing atop, I found things going at a glacial pace, a
wee part of global climate change, and this fine new cron job:
root@box:~# cat /etc/cron.d/atop
PATH=/bin:/usr/bin:/sbin:/usr/sbin

# daily restart of atop at midnight
0 0 * * * root if [ -d "/run/systemd/system" ]; then systemctl restart
atop; else /usr/share/atop/atop.daily \& ; fi

..commenting it out, "brought back life."

..we need to keep an eye out for such tricks causing such DOS.
root@box:~# dpkg -l atop |grep atop |fmt -tu
ii atop 2.2.6-4 amd64 Monitor for system resources and process activity

Scenarios always come in sets of three:
best case, worst case, and just in case.
