This implies that postfix tried to pass the message off to your local  
content filter and could not connect to it, so the message got queued  
up for the next queue run an hour or two later.

You ought to adjust the number in the second-to-last column in /usr/ 
local/etc/postfix/master.cf for your virus scanning task (often  
called scan), to correspond to the number of amavisd children you are  
running, and you should adjust amavisd to only run as many children  
as your hardware can comfortably handle without swapping.
