Hi Pieterjan,
I am currently having doubt on this issue, Is this really a memory leak, or is it just because we don't really know how to free up the DI API objects.
I haven't have time to test on this again.
The new SBO 9.2 offers a web browser access to the SBO Application, in order for our add-on to run, I think we will need some kind of web services.
If it is really what I think it is, then we need to really have a clean code that does not have memory leak.
I haven't look into this feature though.
Regards
Edy
