Ok right, you had a problem. I moved capture to some car to a different server because it was overloaded. Your car got on an instance that shouldn't have had car on it. 10 car were affected.
It would have been resolved tonight also once I moved it to the new data logger. But I've started that server so those 10 car get logging working again now.
I do have monitoring that give me warning if cars are not logged, but not when there is just 10 (as there is a lot of car that are not logged for different reason).
Will try to think of a different way to check for this scenario (though it will be different with the new logger).
