Hi there,

I noticed on my CentOS 8 machine, there are two different services
listed: clamd@multi-user.service and system-clamd.slice. I don't
have enough memory to run the first one, but only the second one

these two services? I only have 2 GB of memory. Is there any way to
run clamd? I get this error when I try to run it ...
You *might* *just* *possibly* be able to run clamd on a system with
only 2G of RAM
It _can_ be done, using cgroups to restrict the amount of memory used,
but it'll be doing a bit of swapping.
For email processing, we run clamd on virtual machines with slightly
less than 3Gb memory, of which clamd takes up 1Gb.
Just a note: until about a year ago I had a mail and web servers running
on a 32-bit Pentium III which had a whopping 768 MB RAM. It did the job,
but over time I noticed that I started getting email increasingly
flagged as "not scanned" due to timeouts by amavisd or clamd. Of course
the system was swapping like hell.
That was the time that clamd "only" consumed 700+ MB, as opposed to
today where it now takes over 1.2 GB in a basic setting.
And yes, the mail and web servers now runs on an 10-year old 64-bit
machine with 16 GB memory. I even have structural CPU time to run BOINC
processes on my server again.
So, 3GB is enough for now as speed is mostly not a real issue. Looking
at the increased rate of memory consumption by clamd and factoring in
the fact that developers of all walks are rather sloppy with memory
consumption, it will not take that many years before you have to switch
to a 64-bit machine with 8 GB or more too.
