I have completed a udp scan on an embedded device in the lab and the
scan duration was 18.22 hours.

The scan syntax used is as follows:

nmap -sU -p0-65535 <ip_addr>

Should a UDP scan take such a long time? Could the scan time relate to
some problem with the device?

No, it would mean the device is responding well within norms.

Archive scan question really, read:
