Server Crashing Help java.lang.OutOfMemoryError: PermGen space

Ok My Server Is Crashing Due to java.lang.OutOfMemoryError: PermGen space

and i don't know how to fix it my server is running 7 gb of ram and my computer has 8 gb it works perfectly fine until someone joins my server

this is my server log: http://pastebin.com/aPuevxdm

i think it has to do with my craftbukkit but not sure!!!! help

 

First try adding more ram to the server. If that does not work go into your start.bat and try to allocate more memory to the start up process. You do this by using this code.
java -Xmx1024M-Xms1024M-XX:PermSize=256m-XX:MaxPermSize=512m-jar craftbukkit.jar

 

Looking at that startup log, here's some things you should do.
You should delete HealthBar, Skillz, CompassNavigation, and SkyWars. They won't start, probably because they use more RAM than your computer can supply.
Also, 13 worlds is probably too many for your computer to handle. If I were you, I'd reduce that number down to 4 or fewer, even with 7gb of ram.
How many plugins do you have total?

 

No, he doesn't need to remove CompassNavigation.

 

1. [14:45:25 ERROR]: Error occurred while enabling CompassNavigation v2.1 (Is it up to date?)

 

The problem with that is that he got an old version of Essentials. Don't blame the plugin author for something he cannot do against.
