No garbage collecting at all I think?

Hey guys, I think there is no garbage collecting going on my server. Ram is staying the same no matter how many people are on the server...

Like when a new player joins it goes up a bit but if they leave it remains the same....

screen -dmS minecraft java -Xincgc -Xmx1900M -jar /home/bukkit/server.jar nogui

is what i'm using to start mc

Please anyone? Have any ideas? Happens every few hours. Server crashes when ram fills up. We are on R4

I don't think it's a memory leak because the data

These are the only errors I could find when it happened...

Code:

A list of the plugins I use...



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

 

Ok, try replacing "-Xincgc" with "-XX:+UseParallelGC". That should speed up performance of the Garbage Collector.

A little bit of info:

"An Object becomes ​

eligible for Garbage collection or GC​

if ​

its not reachable from any live threads or any static references​

in other words you can say that an object becomes eligible for ​

garbage collection​

if ​

all references are null​

."​

So, only when Java is completely done with the Chunk/Block/Player/etc. will it remove it from RAM. I do believe that one or more of your plugins are causing this reference, and keeping the Chunk alive. Try removing all your plugins, and add them back one by one to see which one is causing the problem. If all else fails, add more RAM!

BTW, most people don't know what "Garbage Collection" means, so you may want to look into plugin development. I don't know, just saying...

 

Don't like java....so not really into it

The problem with removing plugins 1 by 1 is it takes quite a few hours for the ram to fill. So wouldnt know for a LONG time...
