Normally I monitor memory usage on all my servers with Nagios, but
that only gives me the overall picture and on a busy server a small
memory leak could hide in the noise.  After reading your post I set up
a cron job on my clamd server to wake up every ten minutes and log the
memory used by freshclam to a file.  This is on Raspbian, but I don't
let systemd get involved in anything that I care about.  The daemons
are started from /etc/rc.local.

I've seen no evidence of a memory leak at all.  The 0.103.0-rc2 daemon
has been running for eight days continuously.  It's currently using
(top, RSS) about 8.6 MBytes of RAM - and 6.9 MBytes of that is shared.
