Hi,

I have tested on several servers with 2 or 3 GB + 1 of swap. Yesterday I
was monitoring with htop and, when scanning a single host, free RAM would
go from 1.5Gb to 20 MB depending on the vulnerability scanned.

Target by target isn&#39;t the issue. Define your range (30 servers is<br>
tiny compared to what I&#39;m scanning) but limit the number of concurrent<br>
hosts and concurrent NVT&#39;s until you find a balance that works for<br>
you. Currently, I limit mine to 5 hosts with 4 concurrent NVT&#39;s and<br>
have no problems running scans from a VM.<br></div></div><div class="im">
