I keep getting these errors at random times. I usually hit peak players at this time which is 100+. My server specs: 16GB RAM (15GB allocated to MC) Quad Core AMD Phenom (Obviously, 1 core) 100MB Port CentOS Java: java version "1.6.0_26" Java(TM) SE Runtime Environment (build 1.6.0_26-b03) Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode) What I use to start CB: java -Xmx15360M -jar craftbukkit.jar nogui Where my data is: /root/mc/Minecraft (I use MCMA but I've had this problem since, so I run CB with the command in terminal) The only plugin I changed was Permissions. I'm now using Permissions 3 instead of Essentials Group Manager. What's the problem? Thanks.
