We ran a scan with the following parameters using nmap 6.26SVN (I don't know the exact revision, but it's from December
nmap -sTUV -Pn -O
outputfile -iL targetsFile
and got the following result
NSE: Script Engine Scan Aborted.
An error was thrown by the engine: /usr/local/bin/../share/nmap/nse_main.lua:898: error in __gc metamethod
(/usr/local/bin/../share/nmap/nse_main.lua:391: Error in setup of iod with proto 17 and af 2: Too many open files (24))

[C]: in ?
The 'targetsFile' included 255 hosts, and the report for each of the hosts was something like:
Nmap scan report for 188.8.131.52
Host is up (0.029s latency).

The last line of output was:
socket troubles in Init: Too many open files (24)
Before switching to version 6.26SVN, we where using an older version of nmap (5.51 I think) and we didn't have this
issue, running on the same set of hosts, with the same parameters. Currently we are trying run on a smaller set of
hosts in parallel (--max-hostgroup 64), to see if this could possibly solve the issue temporally.
Could this be related to these posts ?
