What build of Craftbukkit are you on? What plugins do you have? What operating system do you use? How much RAM does your server have? Can I also have a full error log? Turn off the server. Delete server.log Turn on the server. When you get the error turn off the server (or not -- I guess it crashes when you get the error) Post the entire server.log.
Sorry it took so long to reply im currently trying to recreate the bug! My plugin list is extensive and i dont know if i can name the entire list I use a mac I use build 1060 I dedicate 2000 ram to my server Hope it helps!
If you type /plugins in game, it will write your entire list of plugins into your server.log file. Also, can you post the 5-10 lines that came before the error that you posted? And is the error happening at any particular time or just every few minutes?

@Bloobubba You didn't follow my guide, therefore your server.log is useless. I don't want an entire log. Read my guide again.
