Garbage collection in Flash Media Server

I have memory leak in my project and I wonder how garbage collector working in Flash Media Server.

I have 2 questions:

1. Will FMS release objects from memory that have cycle references. For example when object A is has ref to Object B and vise versa.

2. Why FMS still consumes memory after application unloaded by idle timeout. For example there were no user开发者_开发百科s connected then fms unloaded app after 20 minutes. Memory usage left at the same level (for a long period of time).

In general I miss some best practices of writing FMS code. FMS 3.5.1 on WinXP
