Apparently it is not that code either -- I did as you asked and changed the line 
in with no change in the behavior.  The SA cache was disabled during 
the test as well -- after about an hour/hour and a half, the machine starts to 
run out of memory, starts to swap, and then spirals downhill from there. 
Switching the symlink for /opt/MailScanner back to 4.47.4 or 4.48.4 solves the 
problem.  Also note that I see this same behavior in 4.49.7.
