Hi Are you having any error with running multiple controllers on the same machine? In your case, each controller, must be listening on a different port. For instance, if you have half your network point to controller at port X and other half pointing to controller, you will run the following two programs on the computer:
./nox_core -v -i ptcp:<X> myrouter. ./nox_core -v -i ptcp:<Y> myrouter. Srini.
