net.minecraft.server.WorldConlictException: Failed to check session lock, aborting
Help! How do I fix this! My server is crashing every 5 minutes, I am also getting "Connection reset" nearly twice every second! It could be players trying to connect and not able to, idk, I'm not very good with this stuff...
Here is a list of plugins I have:
-WorldEdit
-Essentials
-Citizens
-WorldGuard
-iConomy
-PermissionsEx
-Bookworm
-multiworld
-ChestShop
-MobDisguise
-AntiSpawnKill
-ChatManager

 

Same problem here, allmost the same problems. Does anyone know, whyt this is ?

Please zip your world, upload it to mediafire.com, and send me the link

Same problem!

Any solution for this?

 

Well it appears to happen when too many plugins try to access the harddrive at the same time. We arent quite sure about this, but we simply reduced harddrive access and its gone for us. I think its a problem within bukkit that only occurs under very specific conditions.

 

BlackHawkLex, forgive my silly questions but how does one "reduce harddrive access" ?

That should work
