Can you tell if Nmap is using the correct source address and
interface? Does it work if you force it with -S and -e?

I ran into a bug with the interface determination code in
route_dst_netlink() somehow leaking file handles and running the box out.

In short:

$ sudo ./nmap --datadir . 
Starting Nmap 5.52.IPv6.Beta2 ( http://nmap.org ) at 2011-06-13 19:49 UTC
route_dst_netlink: cannot create AF_NETLINK socket: Too many open files

But using a /24 works just fine.  To get around this I have to specify
the interface with -e.

I found a socket leak in another place that was causing this. It's fixed
in r24012.
