Having issues with palo alto pa-820. Some times when users try to load sites they just don't load. Wait some time and site usually loads. Some times it is fine, loads fast, users not getting any errors. No changes made to cause issue. Thinking it is something with dynamic updates? This started on the morning of 12-04-2022.

You need to monitor the traffic when it works, and when it doesn't in the firewall. You also want to do trace routes in both scenarios. See if for some reason it is falling down to a deny all. Also, not the protocol being used. I see the most issues when sites try to use quic.

Looking at -Logs -Traffic and my IP and not seeing any deny under Action.
Found this what does "resources-unavailable" under "session end reason" mean?
Management CPU seems to be at 100% all the time.

I think you just answered your own question there. Are you doing ssl decryption? Deep packet inspection?? Those are resource hogs.
