Has anyone heard of this? Could this be a Router or ISP problem??? It took very long to complete because i needed to use the -T Polite option. I'm just curious if anyone else has ever encountered nmap using up all network resources for such a high volume connection. Any help would be appreciated so this never happens again. *Luckily I started after hours* > blue I've seen similar; some firewalls (e.g. WatchGuard) start blocking connections from hosts that generate 'x' policy violations in a given time. Bleh.
