Excessive RAM usage - Memory leak?

    Hey all,

    I have noticed unusually high RAM usage running bukkit on our server.

    5 to 10 players and a period of 2 hours are enough to eat 93% of the allocated 3.2GB

    After Notch fixed the memory leak with or shortly after Beta, RAM usage was below 50%, even with 15 or 20 players and many hours.

    Server gets started, just like before, with default screen -dmS minecraft java -Xmx3200M -jar craftbukkit-0.0.1-SNAPSHOT.jar nogui

    I can't tell if it was always like this with bukkit, but I definitely noticed it since a release around #60.

    Plugins could be the culprit as well, I assume. It's happening right now on the server, with these plugins running: dynmap, General, GroupUsers, iConomy, MCDocs, MyHome, SearchIds, WorldEdit, WorldGuard, Flashlight, Cleaner.

    Any ideas? Others have the same problem?

    First step: Remove ALL plugins. Test your server. If no memory leak, put in a single plugin. Run server again and test. Keep doing this until you isolate your problem. Once problem is isolated and properly identified, notify the plugin author in question, or repost here if its actually a problem with CraftBukkit. Also, version information is needed. (OS version and whether it is x64 or x86, same thing for Java. CraftBukkit build version also necessary.)
