You sure? If you revert that single patch, all is well even after multiple ssh logon/logoff attempts? > But I am not sure what is wrong with this code. No, I don't get it either. > Is this code really necessary? It's probably not necessary, at least we hadn't had anything like that before. As you can see from commits 71b8777a7140, 8eee25241e86, dd3730ed9c1c and bcb33dc4f055, the idea is to unload a user profile if it's not used anymore. I'm puzzled that calling UnloadUserProfile should actually unload a user profile if it's still in use by the interactive session. That sounds like a bug in Windows to me, but what do I know? I can revert this single patch, or I can revert the above patchset trying to unload a user profile entirely, whatever makes more sense. However, what makes most sense?!?
