Re: High CPU utilization by systemd process || Debian 8

[David Anderson <dave@xxxxxxxxxxx>]

Note that Debian 8 is very old. It runs systemd v215, which came out
in 2014. So, from upstream's perspective, unless it's a well-known
bug, the answer is probably "who knows? Use a more recent systemd."

I suggest filing a bug with Debian and asking them for help. Debian 8
is still supported for another 6 months, according to
https://wiki.debian.org/LTS ... Although it's by a team of volunteers,
so YMMV.
