@ExplosiveBacoN Hmmm, never seen that error before, but from what I can tell, looks like a corrupt mob spawner or something, since it's specifically referencing mob spawners and that looks like a corrupted world error. Do you have any mods that can modify the mob that gets spawned, and is this a custom world from single player? Does the crash only occur when you get near a certain area, or as soon as you turn on the server, or as soon as a player tries to connect?
Honestly I have no clue, the problem occurs when the server runs for serveral hours. Also I have the mob limiter plugin and worldguard to prevent mobs from spawning in areas or at all. If thats the cause then I'm screwed, plus I can't really test this since it would have to run all night before the serror would pop up. Edit-------------------------------- Also we run a 24/7 minecraft server with almost 2000 members so this is a servere problem to our uptime and reliability.
Hmmmm, it's probably not either of those plugins, and from the way you say the error comes about it's probably a player wandering within range for the server to load it, therefore causing the crash only when that player gets close enough. Have any backups you can roll back to, because I can't think of any easy ways to fix this one. If it is a corrupted mob spawner like I think it might be, you could probably delete all mob spawners within the world with MCEdit, but I'm not exactly sure.
No backups unfortunatley; crap though, never really relied on mcedit for these sort of things. *bump* Anyone? EDIT by Moderator: merged posts, please use the edit button instead of double posting.
