Walk away from it. Just walk away. It could be gelling and it sweats sometimes. Minor separation generally absorbs back in - if it's a big pool though, you likely got a false trace and will need to HP it. It looks fantastic though.
If it's any consolation, I've been having overheating issues too. I just popped a batch in the refrigerator in an attempt to save it but I think it's destined for the crockpot. Bye bye swirls!
