        empty hash tables:

        18 bits occupy 2MB RAM
        24 bits occupy 128MB RAM

        If the box has 128MB and the bits are 24 the kernel crash is
mandatory, soon or later. And this is a good reason the virtual service
not to be hit. Expect funny things to happen on box with low memory :)
