did it do this with 2.6.4?
you didn't mention verison of SA.
is it SA + sa_updates? or do you have custom rules? (runaway regex), 
compiled rules? or not compiled?

are you having problems with dns rbls?
do you have any ipv6 perl modules loaded when you do not have ipv6? 
(google, I found hard to reproduce problem)
is clamd running? is it slow? did it die?
try to identify the rules and email that are causing the problem

run spamassassin -D against one of the emails.

look at timing. identify which part of sa is causing problem and fix it.
