At random times all TCP connections from the Internet are blocked (all ports and all IPs) for incoming traffic only. Websites, mail servers etc are not accessible from the Internet. UDP and ICMP are not affected. What could be causing this?

You're showing the detailed log entry. (You've clicked the magnifying glass next to an entry in the threat log) To better help point out why this is happening we need to see the main entry. It looks like this is happening because of a VP profile which is attached to a security policy rule.

Can you please be more specific? Zone Pro is the first place we looked and changed various config to no effect.
