Hi guys, Me and my fellows over at the featured PrestoGP-league had troubles yesterday in one of our last pre-season test races. We are working on different theories but hope for any kind of external help. In short, the server started to reject/drop players after we had skipped sessions several times in a row. We usually do 3 practice starts by skipping through the sessions. After those starts, people started to lose server connection. We ran a test race with last build without these problems but with less people ~15 vs. ~25 yesterday. Some theories: 1. Possible new build issue - we were doing fine until the several practice restarts. Logically that says it then less likely matter if 20 players worked at other servers. Maybe we have found a bug that not many will. Maybe a difference in how the application handles connections being made/shut during session switches. Like with memory leakage, the same can be with connections, triggering thresholds for buffer overrun/maximum connection capacity at different application levels (rf being one, windows, router, ...) 2. Router issue - some explanations could be gotten about whenever a single TCP/UDP connection drops, maybe due to connection overflow as in 1) 3. Ive got the not so well informed picture that rf2 is rather sensitive when it comes to correctly set up bandwiths. We got help last time as well as this from people with know-how I believe. 4. Certain drivers' livery or something whole else causing this If anyone could help us find an answer, that would be very appreciated. Thanks.
