Looks like something asked systemd to send sigusr1 to anacron, which is
"clean exit" for anacron. Since the anacron package told systemd to use
"killmode mixed", it waits for a while, then proceeds to SIGKILL
everything in the group because they took too long to die.
It is a bug, but on anacron, not systemd. systemd is doing exactly what
it was (mis)configured to do by the anacron package.
And something *is* asking anacron to restart or to stop. Look at your
log rotation scripts (and also anacron's).

What happens when the anacron service is stopped/restarted under systemd
is different from non-systemd anacron, but that's because the anacron
package misconfigured systemd, so it would be a "systemd thing as
(mis)configured by the package".
But something is triggering that service stop/restart/force-reload
(can't tell which from the logs), and it is not systemd. systemd is
obeying orders from some other system component.
