Hello! The Arduino Create Agent does not have a mechanism to exit if an instance of the agent is already running. This is because during the installation, 2 instances are being run: one for the HTTPS certs install, and the other one is the real agent. See here https://github.com/arduino/arduino-create-agent/issues/217#issuecomment-380022633 Also the agent starts by default on port 8991, if it finds this port already busy it starts listening on the next one, and so on I don't know if this will be implemented in the future.
