Hi to all,

I have an app that is leaking memory (occasionally which is the strange 
bit). How can I use BDS to detect where the problem is or do I have to try 
another third party tool?

Sham.

	It depends on the personality you're using. Is this a C# app? Can you
give more details of the leak?

	Off the top of my head this sounds like you have an object which
implements IDisposable that you (or a component you're using) aren't
disposing (e.g., with using). Collecting will queue it up for
finalization which will dispose the object. But that's a guess.

	Here are some general hints for tracking down allocation issues in
.NET apps:

Yes, CSharp.

Explaining the details are a bit tricky. I have a service that tries to get 
the changes from an ECOSpace using a synchronization server.
In Eco it is EcoSpace.Persistence.GetChanges(). Every time I pass this line 
in the debugger, I see the memory usage go up by 200k. Since I am polling, 
the memory increases.

If I do a GC.Collect(), this does not happen.
