My plugins:

Code:

17:14:08 [INFO] Plugins (26): WorldEdit, vipRanks, TagAPI, mcjobs, Vault, mcworld, MelooonCensor, Multiverse-Core, PermissionsEx, PlotMe, LWC, WorldGuard, BorderGuard, AutoMessage, AuthMe, CommandHelper, bQuiet, AdminPrivateChat, MobArena, Essentials, OtherDrops, EssentialsSpawn, NameTags, AZRank, ChestShop, EssentialsChat

How to fix this problem ? Please Help

 

me too i have no idea how to replicate it,

all i found out is
at net.minecraft.server.v1_4_6.EntityTrackerEntry.track(EntityTrackerEntry.java:85)

this error is where it checks for maps in itemsframes, probably the one showing players arrow on maps on itemsframes

 

Plugin problem. Try getting rid of AuthMe and seeing if it happens again.

 

I am updated Authme, and no result...

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Can i see the server.log file when it crashed?

 

crash server during normal operation, it was checking.

 

What's your server.properties?

 

I am with the same crash problem, I have all plugins updated, only Multiverse-Core is not updated because are not released... Idk if this plugin cause the crash.

 

i have multiverse-core and i have no crashes so its not that plugin i think

 

Also, if you have Essentials. Try doing the commands /gc to check your TPS.
If it's at 20.0 you're good. If it starts to be lower than that then you have a problem.

I'm sorry, but we don't support offline-mode servers here on Bukkit. You'll need to either buy the game, or ask for help elsewhere, preferably the former.
