Hello, we got a race yesterday with 15 driver. Most of the driver must rejoin 2-3 times, before they could join the session. Disconnect during joining for a couple of driver too. Track: Spa (Addon) Car: FR352014 Server Settings: all assists off, automatic clutch on. Root Server: Windows Server 2008 x64, AMD Opteron 3280, 16GB RAM We had in the past this problems with standard tracks, too.
We had this issue recently also after many days of uptime. I rebooted the physical server and it seems to have helped somewhat.
