    Hello Bukkit community!

    Recently I my server has been crashing for unknown reasons when certain players join. This first happened a few months ago. I am usually able to fix it by deleting the given player's file, but I would like to find a more permanent solution, as this seems to be only a temporary one until the next player encounters an error. I am running CraftBukkit version 1.7.5, development build #3042. I am fully aware that development builds are completely unsupported. Part of the reason I came here was to see if I should report it as a bug.

    Here is my server information:

    Version: CraftBukkit 1.7.5, Build #3042 (Development build)
    RAM: 1.6 GB
    Java Version: V7 Update 45
    OS: Linux
    Plugins: 31; WorldEdit, NoCheatPlus, CastleCraftStaffJoin (Custom), Buycraft, mcore, Vault, PermissionsEx, PlotMe, uSkyBlock, WorldGuard, broad-cast, SurvivalGames, CoreProtect, ChestShop, ClearLag, Modifyworld, ProtocolLib, Votifier, GAListener, Essentials, EssentialsProtect, EssentialsSpawn, Multiverse-Core, EssentialsAntiBuild, DisguiseCraft, EssentialsChat, Factions, Multiverse-Portals, HeavySpleef, Multiverse-Inventories, Multiverse-NetherPortals
    Worlds: 7

    One other thing I would like to note is that when this happens, they player reports that they spawn in a void, then they get a disconnection error. This leads me to believe that the world has a corrupt chunk, but in that case, the temporary fix wouldn't be so simple.

    Another question, is it possible to find out which plugin might've done it with the crash report?

    EDIT: I decided to re-read the crash report. It appears there was an error loading NBT data.

    Mike1022 I noticed that too. But I have no solution...

    Just a shot in the dark, but you could try and load your world in MCEdit and try and find the bad chunk and delete, repair, not sure, do something with it.

    As fcernese implies; this issue is generally due to the player logging in to a corrupted/'bad' area

    You could temporarily fix this by going into your world folder, then clicking 'players' and deleting the affected players' .dat files. The issue will reoccur if the player(s) return to the 'bad' area.

    Give this a go:

    Ok, but I don't think it's a corrupt world or it would happen every time the world was loaded, right?

    EDIT: If it is an error loading NBT data, then wouldn't that be like a renamed item or block? Or maybe even a playerhead the person is wearing?
