I am curious what you learn as I have seen similar behavior. I've been nmapping a printer on my local network, trying different things, and nmap freezes for me after a short or long time. Strangely though, it seems to ~ "unfreeze" if I start another nmap instance, probing the same address, in a separate terminal window. Sometimes I have to kill and restart that other instance as it freezes too, but this workaround has allowed me to continue at least. I am on 6.3 stable with latest syspatch.
