Fixed that problem. Now I Keep getting "Can't keep up! Did the system time change, or is the server Overloaded? My server is a dual cpu quad core 3.0 gig. It has 8 gig of mem. I watched cpu load and it does not go over 70% per core. I also get this error when no one is on?
That happens man to everyone, try changing in the server.bat or the file you use to run the server edit it to have more than 2gb of ram.
So it will look like this when done the file may also be called ServerStart. Just choose one of them but make sure in the end you do not add over 6gb of ram in total between the server and client side. Leave 2gb to windows.
java -Xms2048m -Xmx2048m -XX
ermSize=128m < thats 2gb
java -Xms3072m -Xmx3072m -XX
ermSize=128m < thats 3gb
java -Xms4096m -Xmx4096m -XX
ermSize=128m < thats 4gb
Then for your ftb ram make it 3 or 4 gb.
