I run a tekkit server for a couple buddies off my home server box. Everything was running great for a week or so, but then we stopped playing for a week but the server stays up 24/7. Anyways after the, I try to log into it today and it freezes on the login. I closed the Tekkit client and restarted and the server was unavailable now. I look at the log and it says
2012-03-22 10:16:35 [WARNING] Can't keep up! Did the system time change, or is the server overloaded?
Time did change this past weekend? I restarted the server, but still nothing. After a few minutes it gives me the same message. Java is maxing out 1 core of the server cpu.
I tried loading another tekkit folder with the same server properties and everything and it all worked fine, and was able to log in without issue (it generated a new map). Java was using the normal 10% cpu. Any thoughts or imput?
