Crash when file or folder from import gets modified (Memory Corrupt...)

Environment

• Pythonnet version: 2.5.1
• Python version: 3.8
• Operating System: Win10, WinServer (2019,2016)
• .NET Runtime: 4.7

Details

• Describe what you were trying to get done. I have a webservice that invokes a python.py file and gets its result, it works fine, the webservice is hosted in IIS, however whenever I change something from the file or folder where the python file I imported is it corrupts the memory and I have to restart the app pool or restart iis, To import the file I just use: Py.Import(INTERFACE_FILE_NAME); Is there some fundamental thing I’m missing?

  This is the error message I get, it seems to be crashing when the .py file has been modified and it tries import it again. :

System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at Python.Runtime.Runtime.PyImport_ImportModule(String name) at Python.Runtime.Runtime.Initialize(Boolean initSigs) at Python.Runtime.PythonEngine.Initialize(IEnumerable`1 args, Boolean setSysArgv, Boolean initSigs) at Python.Runtime.PythonEngine.Initialize()

What I’ve tried:

What hasn’t worked: Py.Import PyModule.FromString (Access Violations…)

What has worked: Using any of the import methods but stopping the app pool, editing file and restarting the app pool (I don’t like this option)

Could you test whether this occurs on the current master as well?

@lostmsu Right, thanks. It seems settled for now but I’ll keep an eye open.

And for anyone wondering or using IIS: any modification to the files inside the bin folder will result in Recycled App Pools. More here
