The reason for "cracking" in most any finish is the upper film gets hard faster than what's under it, plain and simple in my experience that is what could cause "cracking". The film under the clear has "moved" do to it being uncured and soft, just like the ground moving under concrete, the concrete cracks.
Die back of course as Ray mentioned is most common with this but "cracking" is VERY uncommon these days with Urethanes. So I am just going back to the old standard that when something is hard laying over something that is not, the hard cracks.
