It's not possible to be certain from the code you've posted (you haven't said if you're using ARC, or shown the call stack when using zombies), but if all your menu actions look like this, you will be building up an enormous stack of view controllers on the navigation controller, which is going to lead to high memory use. Depending on the rest of your code this could lead to some view being deallocated which is then later released elsewhere.

Your menu action code should probably install the relevant view controller as the root view controller of the navigation stack instead of simply pushing it.

To help track down what the offending object is and where it was created, you can use the Zombies instrument. When you app crashes, open the detail inspector on the right hand side and it will tell you what the view is, what method it was created in and so forth. This is a great help when tracking these sorts of bugs down.
