Grab the code at www.freebsd.org/~jhb/vm_objects/.  Build and load the kld and 
then use the vm_objects binary to generate a list of the active VM objects in 
the system along with counts of how many active / inactive pages each object 
contains.  For your case with lots of inactive memory, you probably want 
something like 'vm_objects | sort -n -k 2'.
