There are two things you might do to deal with memory over consumption 

Add more RAM to the system

or off load some of the services to other systems rather then directly 
running them all on the firewall server.  And this is likely the better 
way to deal with the problem in my mind.  firewalls afterall are 
traditionally a single purpose system.

The most any of us can do is sign on as it's accomplice.  Instead
of vowing to honor and obey, maybe we should swear to aid and abet.
That would mean that security is out of the question.  The words
"make" and "stay" become inappropriate.  My love for you has no
strings attached.  I love you for free...
