Have had a similar issue. Dedicated Server stays up for some time until after everyone leaves. Then it cannot connect to matchmaker. After restarting it it stays up again, almost seem indefinite, then after it empties out again and everyone leaves, no more connection. Pretty much every afternoon im finding i need to restart the server. Only one rf2 server running. Would it conflict with rf1? Have multiple rf1 servers on there no problem at all. We also have downloads disabled on the rf2 server. Other than that we have not changed a setting.
