each vscan process take 60 - 75 MB.

When the machine is way behind, there is 200 - 300 MB of free + inactive RAM.

On this fbsd 6.2, "Top version 3.5beta12" doesn't show the swap info, "Swap: " is a blank line, but I really don't think the machine is swapping when groaning, looking at the 200 - 300 MB RAM available.

I've turned off pyzor, and left amavis processes at 10. I'll see how it goes Fri morning.
