I've been in pits editing a setup when lost connection from a host. Here's what I see and nothing happened anymore for minutes after that. (My internet connection wasn't down, since I'm writing this right now after that).

The sign reads: "no cars on track". Closed with Alt+F4.

Had this problem as well for a few times... Anyone knows the reason or how to prevent it in future?
