Firstly, hello everyone Ok, I'm trying to run a craftbukkit server at home, just testing things out at the moment before I put it onto a dedicated machine, but I'm having problems even getting the server to start. Running windows 7 64-bit, 4gb RAM, 1.4 dual processor. Java - java version "1.6.0_17" Java(TM) SE Runtime Environment (build 1.6.0_17-b04) Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01, mixed mode) 64-bit Not running any wrappers. This server is running Craftbukkit version git-Bukkit-0.0.0-355-ga67a34a-b266 (M C: 1.2_01) This server is also sporting some funky dev build of Bukkit! As for the command I'm using, just running it through the .bat file I was told to make. Tried changing the java path to use the 64-bit version of java and the x86 version, no difference. No plugins and everything is freshly downloaded today. Here is the error I keep getting: Checking the world directory and it lacks a level.dat file, it simply contains one folder (0) and a session.lock file. Obviously something is going wrong with world gen, not sure what though. The standard minecraft server program works fine it seems. --- merged: Feb 7, 2011 9:29 AM --- Changed the -xmx and -xms to 1024 and it's working now. Sorry to make a topic about nothing
