I would check the value of your Max Heap Size in CF Administrator, the CFMX's memory usage should not exceeds that value, you may have it set too high.
Even though objects may be "freed" by the garbage collector, it doesn't necessarily mean that a proportional amount of memory will be freed in the OS. The JVM allocates memory for the heap which may or may not contain any actual objects. When there is contention for space in the heap - the heap grows until the max heap size is reached.
I have posted some info about obtaining the JVM memory usage info from within CFMX on my blog, see: http://www.petefreitag.com/item/115.cfm
The variable maxMemory is the max heap size, totalMemory is how much heap is actually allocated in OS memory.
