Well its been a year, and 3.x is here, and I'm still saddled with the
unanswerable question of who is holding onto my models!?!
I have a database application. I have my own Editors and parts which are
connected to my database through my custom IEditorInput.
My database items are cached with weakReferences and I can not get rid
of them till everyone that is holding them lets go!
What part of eclipse is holding onto my IEditorInput, and my EditorPart?
If I open and close an editor on 10 different IEditorInputs, _all_
IEditorInputs are still held, and _all_ EditorParts are held as well.
Somewhere. The question is where? And how do I stop this!?

It would appear that you should invest some time using a memory profiler to
find the references.
Or log a bug report with a reproducible test case that shows the "leak"

Its been a year. I invested lots of time. Just dont have money so it
takes more time. In any event after much pain and suffering I have
found the culprit is an internal class NavigationHistory.

Its not a "leak" per se. But then again... The class decides to hold
onto the last 50 IEditorParts opened. Why I don't know. I think I will
file a bug since hitting the newsgroups didn't bring any results last
year either. I would have expected other database Editor type folks to
have similar issue.

Can you modify your implementation so that when the editor gets disposed it
nulls out all of its references to the model etc.
This is what I do for the Ant editor.

Yes, I have been investigating this. I was able to get all but the last
closed editor to have all its stuff freed by calling
getGraphicalViewer.setContents(null) in a partClose listener.
I am setting my models to null, and removing all listeners too. Last
year I discovered some part of the architecture would not let go, so I
just created a sort of weak reference proxy, and let that part hold onto
the proxy. I believe that was due to the recent file list.
This years challenge is the History it would seem.
