FATAL Bad Memory Block.

[Mark Huss <mark.huss () systemexperts com>]

Since updating to v7 , whenever I run nmap on my laptop I get somewhere
between 'a couple of' to 'large streams' of the error above, depending on
the options on the command line.  In between all the error messages nmap
seems to be working ok  and printing out the appropriate messages. I did a
site search and found no mention of this particular error. 

 

Win7 x64 SP1  i7 2620M CPU 4G RAM(>2G available)

 

Nmap 7 seems to work fine on my larger box (Win7 x64 SP1  16GB RAM). Is 2GB
too little to run nmap in now? 

 

Examples:

nmap -p 25 -Pn -v -v -v -Pn  {IP}    -- ( a couple of errors:)
