It is assumed that reference counting fails to reclaim some objects in Charta. We need some reproducible test cases that show this problem.
Currently Charta uses reference counting to reclaim objects that are not used anymore. It seems like this does not work entirely as expected. However, in order to solve any problems we need reproducible test cases that expose this problem. If you have any, please provide them.
Please keep in mind that reference counting is not able to reclaim object graphs with cycles. Also, some operations that erroneously aborted earlier could have left objects dangling without being reclaimed.
