java.lang.OutOfMemoryError

This error appears very random. When I run my server (craftbukkit 1.2.5-R1.0) without plugins I don't get this error. But when I run my server and add plugins one by one the error comes with every plugin. (sometime it comes when I only have 3 plugins on it... sometimes with 20 plugins without those 3)

I have a server from enchantedhosting. There they also don't know what's causing the error and how to fix it. I have 1.5GB RAM and 24 plugins: Orebfuscator, WorldBorder, GroupManager, WorldEdit, NoCheatPlus, Permissions, Vault, TimedMessages, LWC, mcMMO, TreeAssist, WorldGuard, Essentials, EssentialsProtect, SimpleSignEdit, CreativeControl, EssentialsSpawn, HawkEye, Scavenger, BetterShop, ChestShop, EssentialsChat, RegionSelfService, Factions

I tested all my plugins and it's just the server in combination with a plugin wich causes the error.

This is the error:

At enchantedhosting they say I have enough memory.

I have been looking on the internet for a long time and I haven't found a way to fix this.

Please help me!

EDIT: I upgraded the server to 2GB RAM and now I get almost the same error. Now it says thread 5 instead of thread 4...

How can I fix this memory leak?

Please help me

try remove
- Orebfuscator



can you edit run.bat file ?

 

I will try to remove Orebfuscator and no I can't but I can aks the hosting company... They are very friendly.

I will wait and see if the error comes again without orebfuscator.

I still have the error
