You have multiple clamscan processes useing a huge amount of memory.

Yes, I have noticed that. Is clamscan or ClamAV consuming huge amounts of
memory scanning all the 110+ messages stuck in the Mail Queue??
What takes up so much memory is the virus database loaded in memory.
it's common to use clamav daemon "clamd", and use "clamdscan" instead.
That way the virus database is loaded only once and clamd handled the
scanning.
That also causes faster processing, because clamscan may need about one
minute to load and parse the database.
You may need to run clamav with special privileges to be able to scan those
files, e.g. when using "amavis" as intermediate between postfix and clamav,
clamd needs to run with "amavis" group as secondary.
The alternative is use "clamdscan --fdpass" which passes the open file
descriptors to clamd.
