I was using my server very happy, all perfect , but the server started to lag, I dont known why, just started, I did nothing, I tried to open in the better PC with Intel 5 core 3,8 Ghz and 4Ghz RAM but nothing, my connection is 10MB, I use windows XP ( I tried in windows 7 but is the same thing) I dont instaled no new plugins, dont changed config, nothing... i dont known why, dont have any error in the console... Sorry for the very really extreme bad english. @edit if someone want my plugin list just tell...
This is very common (after ensuring it isn't RAM allocation issues) in world corruption. Could you please fill this out and post it back here: http://forums.bukkit.org/threads/you-need-help-we-need-this-information-to-help-you.2018/
