Lua stopEvent causes server crash!

[feverdog]

As the title says, the stopEvent function causes my TFS 0.3.7 to crash.. I have tried everything and more but it crashes. I have tried to reproduce addEvent with coroutines, but when I use socket.sleep the entire server freezes and I couldn't find a way to make it Thread Safe.

Distro: TFS 0.3.7
Platform: Windows

local EXPIRY = 5 -- tempo em minutos para voltar ao normal
local LEVER_AID = 9500
local LEVER = { OFF = 1945, ON = 1946,
	POS = {x=1059, y=1200, z=9, stackpos=2}} -- todo: see stackpos

local GATE_ITEMID = 1546
local GATES_POS = {
	{x=1053, y=1193, z=9, stackpos=2},
	{x=1053, y=1194, z=9, stackpos=2},
}

local MONSTER_NAME = 'Legione Gladiator'
local MONSTERS_POS = {
	{x=1059, y=1197, z=9},
	{x=1061, y=1195, z=9},
}

local monsters, event = {} -- armazenamento
function onUse(cid, item, fromPosition, itemEx, toPosition)

	if (item.aid ~= LEVER_AID) then
		return false
	end

	if not(jlibs.isInArray(LEVER, item.itemid)) then
		return false
	end

	function init(item)
		item = getThingFromPos(LEVER.POS)
		if (item.itemid == LEVER.OFF) then

			for _, pos in ipairs(GATES_POS) do
				local gate = getThingFromPos(pos)
				if (gate.itemid == GATE_ITEMID) then
					doRemoveItem(gate.uid, 1)
				end
			end
			
			for _, pos in ipairs(MONSTERS_POS) do
			    local monster = doCreateMonster(MONSTER_NAME, pos)
			    table.insert(monsters, monster)
            end
            
			stopEvent(event)
			event = addEvent(init, EXPIRY*1000, item)
			doTransformItem(item.uid, LEVER.ON)
        elseif (item.itemid == LEVER.ON) then

			for _, pos in ipairs(GATES_POS) do
				local gate = getThingFromPos(pos)
				if not(gate.itemid == GATE_ITEMID) then
					doCreateItem(GATE_ITEMID, 1, pos)
				end
			end

			for i, uid in ipairs(monsters) do
				doRemoveCreature(uid)
				monsters[i] = nil
			end

			stopEvent(event)
			doTransformItem(item.uid, LEVER.OFF)
		end
	end
 
	init(item)
	return true
end

I have no idea what to do, thanks in advance.

Dont declare event as local and check if it exists before stopping it (if(event ~= nil)then stopEvent(event) end)

Hello EvulMastah, thanks for the tips but it keeps crashing =s

Maybe something to do with the environment? =s I have tried to use setfenv and getenv with no success here and still got crashes.

Could you paste here a crash log?
I guess it should help us to resolve your problem.
