I'm having the same issue of being stuck at block 36079. The only debugging info that I can find that might give a hint to the issue is that there are 6 outbound connections and 0 inbound. Patience and restarts result in the same issue. I'm doing wallet mining to help maintain the blockchain but it says I'm an hour behind. Seems like I can't help solve the next block if I don't have an inbound connection and receiving the latest data.
