We have the server configured with these sessions. Practice 1 Practice 2 Qualifying Race Yesterday running a server with the build 1109, when i changed the session from Practice 1 to Practice 2 all the drivers (16) began to have problems with the server. Nobody could see anyone (like if we where in a private session) and some drivers had a connection lost. I oppened the Remote Desktop, to check the dedicated, and all the pings were bigger than 600. Usually the ping of all our users is lower than 100, and most of us have a ping lower of 50. And we are always the same users. After this, i closed the rF2 dedicated and started it again. When all of us were in Practice 1, everithing was fine again, and when i changed to Practice 2 the problem happened again. I closed the server, all of us changed to the build 1108, i changed the server to the 1108, and started the dedicated. The dedicated server 1108 was a backup that i did before the update to the 1109, and have exactly the same config. When all of us (16) were connected to the dedicated, i passed to Practice 2 and everything was fine, and we continue with the Qualifying and race without any problem. Same users, same server pc, same config in both dedicated, but different build.
