Some people may be targeting your server with numerous RCON password crackers, the only solution for this too make your servers RCON password very hard to guess, also, if there is a keylogger on your computer then make sure not to right down the password anywhere on the computer although it will still be in the server.cfg file, doing this will make it harder for them to obtain your password. Also I wonder if your using the Lux Admin system, as server called De - Drift Evolution had a problem with their Lux Admin script that allowed exploits to gain the RCON password.
