I found and fixed an OS scan bug in r11421. An implementation error disabled global congestion control, leading to large bursts of outstanding probes. With the fix Nmap will not send so many at once. Unfortunately, as I said I can't reproduce the problem so I don't know if this fixes it specifically. If you have been compiling from source please try r11421. Anyone else who has experienced this problem, we could use your help.
I have been using the 4.76 pre-built windows installer, but I can surely build and test it here. What's the preferred build system to make sure the version I try is most comparable to the version I've been using? I have cygwin and msys/mingw32 installed, but I can avail myself of MS VC++ of various versions.
This change could potentially be disruptive for those of you who do large-scale OS scans. I'd appreciate some tests before and after r11421. My feeling is that they will take the same amount of time or will be a little bit slower. David Fifield
