I discovered a memory leak. I reduced my code to this to identify the leak. It appears that Python.Shutdown() does not clear all references and memory. Here is a picture of my memory diagnostics. Do i miss something? Maybe someone of you has some info.\r\n\r\n[Memory diagnostics picture](https://picload.org/image/riwidglr/memory.png)\r\n\r\nHere is my c# code:\r\n\r\n        static void Main(string[] args)\r\n        {\r\n            for (int i = 0; i \u003c 10000; i++)\r\n            {\r\n                Console.WriteLine($\"Cycle: {i}\");\r\n\r\n                Console.WriteLine($\"Status: {PythonEngine.IsInitialized}\");\r\n\r\n                if (!PythonEngine.IsInitialized)\r\n                {\r\n                    Console.WriteLine(\"Initialize\");\r\n                    PythonEngine.Initialize();\r\n                }\r\n\r\n                Console.WriteLine($\"Status: {PythonEngine.IsInitialized}\");\r\n\r\n                if (PythonEngine.IsInitialized)\r\n                {\r\n                    Console.WriteLine(\"Shutdown\");\r\n                    PythonEngine.Shutdown();\r\n                }\r\n\r\n                Console.WriteLine($\"Status: {PythonEngine.IsInitialized}\");\r\n            }\r\n\r\n            Console.ReadLine();\r\n        }\r\n\r\n\r\n","author":{"url":"https://github.com/RomzMcGriess","@type":"Person","name":"RomzMcGriess"},"datePublished":"2017-06-19T11:20:37.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/499/pythonnet/issues/499"}
