Hi, I have my own tekkit server that mostly runs fine, but sometimes in the code a message is displayed that says " (ATTENTION) Can't keep up! Did the system time change, or is the server overloaded? "
Sometimes this message comes several times in a row. All I understand about it is that it causes terrible lag on the server, and most of the time the server works if I stop it then start it again. But sometimes it just keeps coming every time I launch the server and it's getting annoying. So does anyone know any useful information/help about how to fix/prevent this? All help is appreciated :)
