Acrobat craches - how to manage RAM usage?

Question

I implemented a script for switching on and off a lot of lists of my pdf layers to the same time. The Acrobat crashes when I use it with big PDFs, around 60 layers. At first I though it would be an error, therefore I checked all the functions and added exception handling on every function. The program still crashes without throwing any exception( to be sure, I putted app.alert(...) in catch-block). Then I realized that the acrobat crashes if it involves up to 500 mb RAM, on other computer 450 mb. Can it occur at all, that it crashes cause of lack of memory? If yes, is it possible to manage it somehow? (increase more RAM for the program or delete some variables, which are not using more at runtime or there is some garbage collector)? I would appreciate any suggestions.

Answer 1

Do you mean, something like this: var ocgsArray = this.getOCGs(); ?
Could I change/get the properties of each layer on such a way as well?
i.e.:
1. ocgsArray[1].state = false;
or get the name :
2. var layerName1 =  ocgsArray[1].name;
