startScript re-entrancy has exceeded 3?

I'm making an eye that is supposed to pulsate, however, I keep getting this error. It's really weird, as I've never seen it before.

Script;

local eye=script.Parent:Clone()
eye.Parent=workspace["Wisdom Fate Gauntlet"]
spawn(function()while wait() do
    eye.Transparency = 1
    eye.eyeMesh.Scale = Vector3.new(0.35, 0.35, 0.35)
    wait(1)
    eye.Transparency = 0
    for i = 1,10 do
        wait()
        eye.eyeMesh.Scale = eye.eyeMesh.Scale + Vector3.new(0.01, 0.01, 0.01)
        eye.Transparency = eye.Transparency + 0.1
    end
end
end)

I've read upon it and they say it has something with too many clones, but there's no loop or anything causing too many..?
