Exception During World Tick - Server Crashing

Discussion in 'Spigot Help' started by ShadowKingdom, Jun 5, 2017.

  1. Hello,

    My server has been having an issue with crashes. This issue seems to be happening every few minutes, and doesn't seem to be being caused by a plugin. The server CPU and RAM is not an issue.

    In short, this error shows in the console, then the server reboots itself:

    Spigot version: [06:26:19 INFO]: This server is running CraftBukkit version git-Spigot-3fb9445-2b6c9f4 (MC: 1.11.2) (Implementing API version 1.11.2-R0.1-SNAPSHOT)
    If any other relevant information is needed, please ask.

    If anyone can help me resolve this issue, it'd be greatly appreciated.

    Thanks,
     
  2. Update spigot + run MinecraftRegionFixer for your worlds
     
  3. We're running the latest version of 1.11.2, I believe. Do you suspect it's a corrupted chunk? Do you know a way to locate the chunk that's causing the issues? Unfortunately, the crash logs aren't saying much.
     
  4. I do suspect it, yes. MinecraftRegionFixer can locate and remove corrupted chunks.

    But first, try:
    1. Stop the server
    2. Remove usercache.json in server directory
    3. Remove session.lock in world directory
    4. Start the server
    5. If that fails to work, check the world with the tool above.
