[ArcEmu] Freezing

[Pedregon]

ArcEmu keeps freezing whenever I add a custom lua script;
when i'm attacking the npc that uses that script.

It freezes and closes.

+ 4 rep to anyone who can help

Luas;

function Orcshaman_OnCombat(pUnit, event) 
pUnit:SendChatMessage(12, 0, "I call upon the spirits of the elements! Let me use your great power to vanquish this foe!")
pUnit:RegisterEvent("Orcshaman_Lightning", 2000, 100)
pUnit:RegisterEvent("Orcshaman_Heal", 3000, 0)
end

function Orcshaman_Lightning(pUnit, event)
pUnit:StopMovement(2100)  
pUnit:FullCastSpellOnTarget(37273, pUnit:GetRandomPlayer(1))
end

function Orcshaman_Heal(pUnit, event) 
if pUnit:GetHealthPct() < 50 then
pUnit:FullCastSpell(38330)
end 
end

function Orcshaman_OnDied(pUnit, event) 
pUnit:RemoveEvents() 
pUnit:SendChatMessage(12, 0, "Damn...") 
end

RegisterUnitEvent(17936, 1, "Orcshaman_OnCombat")
RegisterUnitEvent(17936, 4, "Orcshaman_OnDied")

Does this happen with other scripts too or just this script?

If it's only this script then obviously there's something wrong with it; post it here/on pastebin if you want us to help you.

Otherwise post the crashdump (the callstack, where it broke and such).

As Dynashock, it either a buggy script and done wrong, or its a core bug causing any scripts to crash the server.

Sorry Ground Zero, I will in the future.
Posted the script, it's worked before, I don't know why now.

Posted the script.
