i created a exp ring.

function onDeEquip(cid, item, slot)
local rate = getlevelRate(cid)
if (item.itemid == 10502) then
doTransformItem(item.uid, 2121, 1)
doPlayerSendTextMessage(cid, 22, 'Sua experiência extra acabou.')
doPlayerSetExperienceRate(cid,rate-1.2)
unsetLevel(cid,1.2)
end
end

function onEquip(cid, item, slot)
local rate = getlevelRate(cid)
if (item.itemid == 2121) then
doTransformItem(item.uid, 10502, 1)
doPlayerSendTextMessage(cid, 22, 'Agora você está ganhando 20% mais experiência!')
doPlayerSetExperienceRate(cid,rate+1.2)
setLevel(cid,1.2)
doDecayItem(item.uid)
end
return true
end

(There are some functions that i made), when its decay its crash the server, and gives erro movementnEquip, stack overflow. I use TFS 0.3.6pl i already read a lot but i havent found a solution =s.
