As a matter of fact, yes I will.  The only two settings I changed are

        max-cache-size 20971520;
        recursive-clients 500;


The max-cache-size takes a value in bytes of the maximum cache size. If 
it reaches this limit, it will expire the oldest entries before their 
TTL in order to save memory.  The default on this is UNLIMITED. So do 
set it.

recursive-clients is the max number of simultaneous recursive clients 
allowed to be connected via udp at any one time. This takes an integer 
and its default value is 1000.

I put these in the global options section.  So far it is working. BIND 
is taking significantly less memory so far than it was.  However, it is 
still slowly rising, so I will continue to monitor the issue.
