Help with Server RAM

Hello.
I have write a plugin with a friend. This plugin makes a new world after a pvp-round. Now its our problem, that any time, we generate a new world with this plugin, the server ram is going higher.
We unload the old maps and delete them from the server.

Code:

if(oldmap != null){
        Bukkit.getServer().unloadWorld(Bukkit.getServer().getWorld(oldmap), false);
        misc.deleteDir(new File(oldmap));
        }

Please help us. In the next time i'm not online many times, because we have holiday *-*

greetings from germany.

 

I guess that's the wrong category for your problem, this one should be fine: http://forums.bukkit.org/forums/plugin-development.5/

 

try reloading the server after? Or possibly a restart.

 

Reloading ans restart empty the RAM, but it's not recommend to reload the server after every game!

Sorry for wrong topic.

 

Is garbage collection not cleaning it up?

 

What is the garbage collection?
Can you explain it, please?

Thanks

 

garbage collection is exactly like the truck that comes around every week to your house and collects your garbage. In minecraft, it gets rid of garbage floating around in memory space, so that it can be utilized better by tasks that actually need it. Many applications use some form of GC, otherwise they would get clogged up with useless stuff.

It's pretty much a sweeper, which cleans up any debris that falls out of a Bukkit truck, so that another can use the road efficiently

 

Okay. How can i clean the RAM with it? Command example? Thats all what i now need. Thanks

 

Garbage Collection is a process done by Java, this isn't bukkit's thing so therefore you can't use a command to do it.
