Title: 100% CPU Load after 10 Mins server

Version: 3.1.2

OS: Ubuntu 11.10 64bit server

Java Version: 1.0.6.0_24 (openJDK from apt-get repo)

Description of Problem:

The CPU usage of ONLY 1 CORE goes up to 100% after about 10-15 minutes of the server being online.

There doesnt seem to be any reason why it happens. It was working fine and then on Saturday night the usahe suddenly went up to 100%, and within 15 mins of server start since, its up to 100%.

Nothing is posted in teh log about it at all, only "Can't keep up! Has..." when I try to do something

How should I go about fixing this. my VPS host and I don't understand how this happening, and we have both run servers before.

Error Messages:

Nothing at all

Error Log:

Doesn't post anything relevant

are you using top to view usage?

and if it happened that night then it must be something that someone build or did in the server.

you can try loading a new fresh generated world to see if it remains high, if the cpu usage goes back to what you expect then it is something with your world
