Hey.. Maybe someone could help me with this problem. This happens to every User on my server. After ~30 minutes they get disconnected with "java.lang.outofmemoryerror java heap space" error. This does not happen to me, but it starts stuttering. This only happens on my server, not on others. My plugins are: Autosaveworld, BKCommonLib, Chestshop, Craftbook, Essentials, HomeSpawnPlus, iConomy, LogBlock, mcMMO, Minigames, Multiworld, NoLagg, PermissionsManager, WarpPortals, WorldEdit and WorldGuard. Heres the server.properties if you need it.. generator-settings= op-permission-level=4 allow-nether=true level-name=world enable-query=false allow-flight=false announce-player-achievements=true server-port=25565 level-type=DEFAULT enable-rcon=false force-gamemode=false level-seed= server-ip= max-build-height=256 spawn-npcs=true white-list=false spawn-animals=true hardcore=false snooper-enabled=true texture-pack= online-mode=true resource-pack= server-id=unnamed pvp=false difficulty=1 enable-command-block=true server-name=Unknown Server gamemode=0 player-idle-timeout=0 max-players=20 spawn-monsters=true generate-structures=true view-distance=10 spawn-protection=0 motd=verticaLs World Don't have much players on my server, mostly 2-3. Would be nice if somebody could help me solving this problem!
