    I have a client who did the same thing - with an Extreme switch. I imagine
    it's a problem similar to the AIX problem, where the device allocates
    memory to each attempted port until it runs out of memory and crashes? We
    also have an ADSL router that behaves this way. The solution seems to be to
    ensure that the scanner tears down the session properly rather than
    executing a stealth scan IMHO.
