Recently started upgrading our 3850's to 16.3.6 and now seeing OSPF failures every 2-4 days. Randomly the adjacency will fail after the Palo is not seeing 4 hello. Then it takes 20-30 minutes for the adjacency to come back.
Any else seeing this behavior? Palos are running 7.1.10 except for one that is running 8.0.9
