Memory management: what happens on scene change?

I'm more familiar with objective-c and iPhone programing, and not so familiar with javascript (even though it's easy).

My game seems to slow down after every scene change, and ultimately it crashes after changing scenes 5 - 6 times. At one point it used to crash after the first scene change.

Once I removed occlusions and view areas... it stopped crashing after first change and now crashes after a few changes.

Is there some memory management I need to do before scene changes?

 

Also, I just used Mac OSX's Instruments to test performance and it seems after every scene change the app increases the "real memory" by 5mb.

So when I start my game it's taking 19mb right away.. after a few scene changes it's up to 50mb ... then crashes at around 60mb.

Are my scenes not being destroyed from the memory?
