Solved Bukkit server crash "Exception in server tick loop"

The server was running fine for several hours, then I modified a config file for mc bans and did a /reload, all seemed fine, but then I stopped the server and now when I start it again I get the following error report. I tried deleting the mc bans config folder (as I had hardly changed anything in it), still get the exact same report though. Any help?

Really need help with this :/ Can't think of what to try! I've got a new version of craftbukkit in case that was the issue, no joy.

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Remove the ip from the server-ip= line in your server.properties file.

 

Immediately fixed the problem, thanks very much. No idea how that happened, might have accidentally pasted it in or something. Thanks again!

 

Can you help me? I have the same problem but removing the ip did not work for me.
