Discussion in 'Spigot Help' started by lilmikey0174, Apr 15, 2018.

  1. My server randomly crashes and I cant find out why!
    this is what happened in the .log: https://hastebin.com/remihelaqo.md
    If anyone can help me with this it would be greatly appreciated!
     
  2. How much ram does your server have?
    Have you run and timings reports?

  5. Any time it says something about a chunk I think its a corrupted one but I have been wrong. I really don't know how to read those errors. MCEdit can fix Corrupted chunks.
     
  6. I made a brand new world and I got this error: https://hastebin.com/utadidiqoz.md
     
  7. You will need to provide /plugins for someone else to help.
     
  8. Try to start without any plugins and a fresh world, Also looks like some lovely chunk errors

    [07:25:53] [Spigot Watchdog Thread/ERROR]: Failed to save chunk (You have a few of them, Never good)
     
  9. How can I fix them?
    EDIT: I already reset the world and disabled all the plugins I didn't have before the crashes started.
     
  10. You need to disable ALL plugins.

  11. Even ones like EssentialsX and PlugMan
     
  12. All? What am I missing? @CGIGaming is pretty good, follow instructions.
     
  13. Yes, especially PlugMan. I hope you have not been using PlugMan to reload or anything while you figure out why you are crashing. You shouldn't use PlugMan at all really. The failed to save chunks could be a full ssd/hdd. Remove all plugins. /restart and test. Start adding them back in starting with perms and other security/core plugins. /restart and test between each one until you find the one that crashes things. And check your drive space availability and other system things if you don't find a plugin that is the cause.

  14. I use PlugMan unload and load is that bad :O

    I don't delete the directories of plugins I delete :I
     
  15. Very very Bad! It literally Breaks Plugins and corrupts worlds and what is :I? Is that some sort of extended Windows Drive Letter?

  16. :I is an emoticon. Sorry for being way to informal.

  17. I'm a idiot, I honestly never seen :I as a Emoticon. What is it's graphical equivalent? MD_5 or whatever this site uses as Emoticons is not listed as that. I did find ( :| = No Emotion) with a Google Search.

  18. If you move the plugins the Dir's are Null so that's ok.

  19. In regards to PlugMan please read my posts in this thread.

    You can save those directories as long as they dont contain huge amounts of data that could be filling up your storage drive. When you find a plugin that is causing problems you can update the plugin and see if it helps if not then delete that plugins data directory and see if it helps. Otherwise find an alternative.

    The problem with a full drive would depend on your setup, if you have your own server then you could just have too much on it. If you use a shared host then someone else on the same node could be filling up all of the storage. Any good host will monitor for this on shared servers so it is probably not the case unless you manage your own dedicated machine then it is up to you to monitor it. You need to eliminate the posibility of a plugin causing the problem. Then if it is not plugin problem submit a ticket to your host to check on drive space. Or check yourself if it is a dedicated server.

  20. The only reload functons you should use are the ones built into the plugin themselves. To add or remove a plugin you should never use ./reload always ./stop
