Any help please, thanks!

 

Do you get that error Right when you start? If not, please send the Full log, at when it starts

 

MightyMocha No it crashes at random times it can happen within an hour of up time or the server can last all day.

Full log of that instance: http://pastebin.com/n8m3jays

 

Your problem is probably in one of the plugins ... Re-Add each plugin one by one and pinpoint the error.

Just looked at the log... Your server doesn't crash at you just get disconnected. I suggest you check your network connection and/or id the problem persists rent a server host on the internet. It's easy and reliable.

It ran out of memory when i logged out

I will be getting a host in the future but this shouldn't be happening.

 

Hey, know this is a bit late, but this is virtually the same issue I'm having at the moment, almost 50% of plugins the same, except I'm running a hosted server. Did you find any plugin issues at all?

 

It is most-likely due to a poorly programmed plugin. Your best option is to isolate your plugins to determine which one is causing the issue.

But as a temporary bandaid (though I don't recommend relying on this as a permanent fix), you can specify the amount of RAM being used in regard to this.

Example parameter:

Code:

-XX:MaxPermSize=128m

So, to start the server with 4GB of RAM, you could use this command:

Code:

"C:\Program Files\Java\jre7\bin\java.exe" -XX:MaxPermSize=128M -Xmx4096M -Xms4096M -jar craftbukkit.jar nogui

Here is a start.bat file I use on my Windows PC:

Code:

@ECHO OFF
SET RAM2USE=4096
CD /D C:\CraftBukkit\
