    Hi,

    I'm new to the Spigot forums, so I hope I'm posting this in the right place; I'm pretty sure this is the right place to post this. Anyway, I run a small private server and I ran into an error when updating it and plugins to the latest version. I'm not very good when it comes to reading errors, so hopefully someone kind might know what this is saying and how I can fix it. Here is a link to the error. http://pastebin.com/9xNwY6n1

    Thanks in advance for any help, it's greatly appreciated!

  2. Code (Text):
    it.unimi.dsi.fastutil.longs.Long2ObjectOpenHashMap.containsKey(Long2ObjectOpenHashMap.java:394)
    Or in simple terms, the plugin that I assume is called "fastutil" is the issue

    So I'm assuming since "fastutil" has something to do with the java api (from a quick google search...), and it isn't even in any of my folders from what I can see, I'd need to contact my host about this?
     
  4. Sorry, I just did a quick google search.

    There is no plugin 'FastUtil', its embedded in the minecraft server. Give me a few more minutes to try to identify the problem in greater detail

    Edit: Maybe a bit more, got to download the latest spigot
     
  5. com.massivecraft.massivecore

    MassiveCore is the problem, I believe.
     
  6. The server doesn't freeze if a different thread is being used.
    It appears massivecraft core has a few threads in the background in order to minimize performance impact from file operations to the harddisk.

    In order for the server to become unresponsive, the main thread must be stalled for some reason. Here is the stacktrace for the main thread (called Server thread)

    Is there anything I can do to fix it, or will I need to just use a different build?
     
  9. Try updating everything, and if that doesn't work, take a back-up of your plugins and delete them one at a time.

    I'll try this and post back when I finish.

    Yeah it looks like a plugin was causing it. It worked fine on 1.9.2, but I guess it doesn't work on 1.9.4. Whatever, I'll just wait for another update. Thanks for those who helped out, I appreciate it.
