    I keep getting this randomly on my server. It lags the server out until finally you just can't connect and it just says "logging in..." and then won't join.
    Plugins:
    Worldedit
    Permissions
    Essentials
    Essentials Spawn
    Worldguard
    Clear
    Essentials Chat
    BorderGuard
    SignColors
    BukkitContrib
    PermissionsSql
    MobDisguise
    Factions
    Hereos
    NoCheat
    The server doesn't lag AT ALL unless it gets this error. It happens even when I don't have much plugins on :/ also all my plugins are FULLY updated

    Now im getting this
    Code:

    It looks to me that your craftbukkit has been Modified. Download a fresh craftbukkit then try again.
