Start with the attached C#.log.txt and the reported DotNetAcquisition log, then inspect the NodeIPCMutex stack location in the extension's dist/extension.js. Reproduce the repeated EADDRINUSE lock error on Linux and determine what behavior should change; done means the criticised error no longer keeps appearing in the reported scenario.
