I am currently trying to scan blocks of IP addresses in Zenmap v5.21.
However, Zenmap keeps on switching to "not responding", CPU utilisation
jumps to 50% and the programme hangs until it is manually closed out. I
not scanning relatively large blocks of IP's when this happens and it can
happen with as few as 254 addresses.
This is the same problem I am having, sadly I can't find much more about
let alone a fix:
I am running it on Win7Pro, when I scan addresses individually or in
chunks of 10-40 IP's it works OK, but I have thousands of IP addresses to
get through and this is just not feasible right now.
Is this a known error with Zenmap and is there a work around? Maybe I am
doing something wrong?
Do it happen only when opening the Topology tab? That's a known user of
CPU and memory.
Maybe you can send an XML file that demonstrates the problem? Just run
your same Nmap command from the command line, adding "-oX output.xml" to
save to a file.
