We've been using Jacques vserver tools for quite some time, but would

It's not a userspace issue;  it's a #define in the kernel-patch that is
currently set to 16.

Paul,

Here are the necessary changes right now in Jacques tools, part one 
refers to the change is in the kernel-patch:

   1. Edit kernel patch to change

           +#define NB_IPV4ROOT    16
       to
           +#define NB_IPV4ROOT    32
   2. Edit tools rpm source (vserver-XX/chbind.cc)
              
           unsigned long addrs[16],masks[16];

       to
                 unsigned long addrs[32],masks[32];
                       if (nbaddrs == 16){
                               fprintf (stderr,"Too many IP numbers, 
max 16, ignored\n");
       to
                   if (nbaddrs == 32){
                               fprintf (stderr,"Too many IP numbers, 
max 32, ignored\n");

Part 2 refers to the changes to Jacques tools...we tried to make similar 
changes to Enrico's tools, but would either receive "unknown error" 
errors or it would seg fault. Most likely because I am not a programmer, 
so my knowledge is limited. I will try and work with his tools further 
to fix this problem, I was just hoping someone had already went through 
this. Thanks...
