Thanks for the tip, I found the issue, it was that clamav-daemon was
running out of memory, crashing & serviced was indeed restarting it (only
for it the crash again & so it went).

yeah, clamav needs a ordinary amount of memory where others drive a dozenzs of production severs with the same hardware...

Since upgrading I'm found clamd is spiking and staying put at 100%.

I've deleted all files in /var/lib/clamav & re-ran freshclam only to have
the same issue occur on the next inbound email?

note that some time after start, clamd loads, virus signatures from disk
unpacks them and builds in-memory databse, so it is expected to eat 100% of
CPU for a few minutes.

logs spew out repeats of the below continuously?

this looks like either the clamav process is crashing, or there is an error
related to how clamd is started from systemd, so systemd kills it and
starts
it repeatedly again  and again...
