I'm having the same issue.  Can't seem to catch on to run through the 
queue in debug mode.

What is happening on my system is this:

Load average jumps from 0.23 to > 20.0.  Sendmail starts rejecting 
incoming messages due to load.  Everything starts to timeout such as 
file checks.  When I run top, I see that it is running the virus checks 
when this starts to occur (I'm running clamd, bitdefender, and avg). 
There are a lot of find processes running as well which is also eating 

After is chews through the email, all jumps down to an average load 
around .2 and then processes everything normally.
