Another hint: if your model uses the standard Gecode search engines, you can inquire how much memory is occupied by the nodes of the search tree. If there is a huge difference between what is reported by the search engine and what is reported by your operating system, you program just has a memory leak.
Then, how deep is the search tree? How many variables and propagators does your problem have? In the end: we could say much more if you provided a little bit more detail about what you observe. The information that your program uses a lot of memory is not that helpful in itself.

Note that that will not help if your problem is due to a memory leak in your program.
