what runs on :7545

FlowAnalyzer UtilityServer is registered on port :7545 over tcp and udp to Fred Messinger. We don't have a technical write-up for it beyond the IANA registry entry.

In nmap's internet-wide scan data this port is never observed open, so if it's open on your network it's more likely a custom or misconfigured service than the registered one.
