What does "Reason - 7" mean?

[Bonne_Swe]

Hello! My server just got DC'ed, just in-mid driving with no obvious reason ( dont remember if someone just joined at that time ). Everyone got kicked out and the gamelog.txt says:

00:45:17.180 : [MP] Session closure requested (reason - 7).
00:45:17.182 : [MP] Session closing.
00:45:17.183 : [MP] Session closed.

That's all in my textfile for the reason about the closure.

I didn't quit game, just went into convoy again and restarted. Up and running again like nothing.

But when I google and try to use SCS's searchbar, I can't find anything what "Reason - 7" is. When I use SCS searchbar it shows all post with the word "reason", and if i remember correctly there were like 110.000 posts with that word. Or something similar.

Anyone that can tell me what "Reason - 7" is? So that I can learn from it and understand it for the next time.
