I have a bukkit server running 733. Something strange happened a couple days ago, a player on my server started to get extremely low fps, and this affected the whole server choking it completely with 100% use. I later realized that the player was not the problem, some of the chunks in the area he builds in causes players entering it to lag extremely, and take the server with him. I tried a clean install on bukkit 733 without any plugins, still no go. I tried MCEdit, Relight function and also deleted big chunks of land to see if this helps, still no go. Tried Repair regions, none were broken. I'm all out of ideas... anyone heard of anything like this. I've searched the forums for hours without luck. Any suggestions is appreciated. I just found this, sounds alot like my problems... but this is from November... http://minecraft.novylen.net/?p=122 EDIT by Moderator: merged posts, please use the edit button instead of double posting.
