Comment 4 for bug 1691971

Done some more research on this issue.
The main reason is inspector runs the werkzeug.BaseWSGIServer which in turn uses socketserver.BaseServer that, upon connection error, prints(!!) the error and traceback in socketserver.BaseServer.handle_error.

Once inspector adopts proper WSGI server, this should be an issue no more.

On the bright side, similar issues were addressed in HAProxy configuration for OpenShift before[1][2]
