Getting a weird issue with the new omada software. The software will start fine, but at some point, tries to restart itself and fails because mongo was already started. Up until it tries to restart itself, the software functions fine.

I don't see anything triggering the restart in systemctl (ubuntu VM). In fact, the status of omada service in systemctl says the service started fine.
