        Is Modded: Definitely; Server brand changed to 'CraftBukkit'
        Type: Dedicated Server (map_server.txt)
    I don't know what causes this, and I'm running multiple servers where it doesn't happen.

    Does anyone know what it happens?

    Anyone?

    This is not caused by ur server. This is ur launcher, I got this problem too, but my launcher updated.

    No, that IS the server :) The server crashes - not my client.

    This is caused by one of your plugins doing something in an async method incorrectly. The best way to find out is through trial and error (removing plugins one by one until the error goes away).

    Is PluginCatcher any use here mbaxter or am I not understanding its purpose properly?

    If you can downgrade to beta 0.2, you can run PluginCatcher (I haven't pushed the update live for some of the changes that were added after the beta, but could compile that for you tonight if not).

    http://dev.bukkit.org/bukkit-plugins/plugincatcher/

    Add plugin, restart server, wait until plugins/PluginCatcher/async.log gets some entries. Pastebin those entries and tag me. They might a) log the wrong plugin b) be very confusing, so it's best to paste it here so I can see it.

    mbaxter, nothing is getting written in async.log, but the console.log is being spammed with all kinds of things from console.log. The server has been crashing three times with the plugin active, but it was first installed yesterday.
    I've pasted the contents of latest.log to pastebin: http://pastebin.com/VdZWvpnn

    The server should be running the beta 0.2 :)

    Sorry for the delay, but it's not actually my server, I'm just from the game host that hosts this server. The owners of the server didn't want me to mess around with it before yesterday.

    You waited so long to read the message that I'd uploaded a new version that only works on the latest dev builds of CraftBukkit ;)

    Looks like something called RegenBlock is causing you some trouble. I'd suggest reporting the async getBlock calls to the author. I also set the thread to 'watched' so I get a notice for every message here. :)

    Thans for the help! I've given the owner of the server a heads up, and they'll look at it tomorrow :)
    I think that plugin is gonna be very helpful in the future!

    Keep in mind that when it's running, it is slowing things down a bit. Definitely great when you're getting crashes because a slight slowdown beats crashing all the time, but I wouldn't suggest leaving it running at all times.
