Nikto open ports

[noa () imperva com]

Hi,

I used nikto to test a specific open port on a server. I ran the exact same test mutliple consecutive times, starting 
the next test immediately after the current one ended.
I saw that after a few tests, nikto replied that there was no HTTP port on that server...
A closer look revealed that the previous nikto test left the ports open so I'm guessing that the server stops 
responding because of too many open ports.
Has anyone encountered this behavior? Do you know whether nikto does not in fact properly close all connections?

Thank you,
Noa
