I was examining the Administrative Log for the Live account we're trading and I noticed something like a 25 second disconnect with the previous connection status being changed to: ServerMessageBacklog. What does that message mean?
It means the api was not able to deal with data as quickly as the server was sending it to you. If you are stepping through code with breakpoints then this would make sense. If it was running on its own then it means however you are handling the events is too slow. If the API determines it is more than 30 seconds behind it will automatically disconnect and reconnect on the off chance that the issue is to do with one of our servers.
