Freeing objects after erase.

[tech]

I want to purge objects after erasing them to free up allocated memory. 

 productMgd.Erase();
 var erased = new ObjectIdCollection();
 erased.Add(productMgd.Id);
 database.ReclaimMemoryFromErasedObjects(erased);

This is happening within a single transaction. When the call to ReclaimMemoryFromErasedObjects(...) is reached, I get the error eInvalidOpenState. Any examples of using this method? Can anyone shed some light on why this error is being returned. The object is stored in a dictionary, not modelspace.

The doc says:

> All object ids in the collection must correspond to erased objects, which must be entirely closed. 

So I think you should commit your transaction before calling this method.

Here is a blog post which shows an example of reclaiming memory of erased objects:
