16x16 Blocks (Chunks?) Randomly restting,

    Hello. Running CB 300+ and a slew of plugins (see second screenshot) on a dedicated server. The only added plugin since the introduction of multiworld support has been MultiVerse, and only since then have we been getting this issue. We have three worlds on our server and it happens in every world all at once.

    Once in a while, on a server restart/crash, the world will randomly de-load chunks (16x16 areas, top to bottom of map), as if it is starting fresh in these small areas. (On the minimap, you can see the large, blue squares that have appeared, replacing the grass and cobblestone walls we made with a sea-level square of ice). The server is auto backed up every hour, but we want to know if there is a way to prevent this or if anyone else is having this issue? Thanks!

    i can confirm this, since 300+ builds and multiverse installed.

    Here's a better, daylight shot. It doesn't seem to care about biomes either, and it is widespread throughout the map(s).

    I would assume it's a multi-verse issue. I would ask it's developer(s).

    I have this same issue, its really bad. It destroyed 2 major projects.

    I am not using any multi-verse plug ins.

    @drew: What other plugins does your server use?

    Essentials - Permissions - Treehugger- magic carpet - skypirates - elevators - voxelsniper - npctrader - iconomy - heroicdeath - milkAdmin.

    Would you mind sharing the script and/or plugin you use for auto backup every hour?

    I had this happen to me just recently, and I'm almost positive it has little to do with specific plugins being installed due to the fact that I haven't changed any of them recently. I'll give a list of plugins and a Java error I'm almost certain is associated with these chunks in a second, just let me actually hop onto my server so I can copypasta.


    Alchemy ; AutoRepair ; Dynamap ; EmptyBucket ; HeroicDeath ; MCDocs ; Minecart Mania Core/Stations ; Murder ; PumpkinDiver ; SlowHealth ; Wormhole X

    This deserves its own thread. Lemme look where to post it and I'll update this post.

    Back on topic: From what I've gathered through experiments with backups yesterday, the broken chunks will stay in the same place but sometimes change constitution every time the server reloads. As far as I can tell, this can only be re-mediated through diligent and constant map/world backups until Bukkit and the like becomes a bit more stable.

    I am having the EXACT same errors on my server as well, and the only plugin we both share is WormholeXtreme. I do not think this is WormholeXTreme - I too think it's something else.

    I use SimpleServer wrapper for whitelisting and backups as well, which may have something to do with things, but I find that unlikely... I'm thinking it's Bukkit.

    My server crashes at random, sometimes after a few hours, sometimes after a few minutes.
