Dell 1950, 2 x 2.00GHz "Woodcrest" 5130 Xeons with 2 cores (so 4 cores total), 
8GB RAM, 8GB swap (I have four of these boxes doing our scanning, load 
balanced).  The problem is the clamscan processes take so long to finish 
scanning that the queue starts to pile up.  I see about 10-15 clamscan processes 
running using fairly low amounts of CPU (even though there is free CPU to use). 
  I've changed the batch size back to 30 to see if that makes any difference, 
but so far it seems identical to the behavior I've seen in the past.  After 
about 5 mins of running, I see:

  1699 root        1 112    0 26400K 19964K CPU1   3   0:01  3.37% clamscan

  1872 root        1 -16    0  8656K  2180K wdrain 0   0:00  1.50% clamscan
  2006 root        1 120    0  8656K  2180K RUN    0   0:00  1.49% clamscan
  1867 root        1 -16    0  8656K  2180K wdrain 3   0:00  0.81% clamscan
  1848 root        1 -16    0  8656K  2180K wdrain 0   0:00  0.76% clamscan

I can't even catch a f-prot process in the process list via top as it runs so 
fast.  I remove "clamav" from the virus scanners list, restart MS, and within 5 
mins or so the queue is back to normal levels.

..which is why I was trying to use the Perl ClamAV wrapper thing, but MS doesn't 
detect it even though it is installed properly..
