Re: Scaling Max IP address limitation

Ok I have tried it on a Pentium-M ( 32 Bit ,) with 512 MB RAM and Core
2 Duo with 1Gig RAM ( running SMP kernel , 2 CPUS) with same results.
Cant go more than ~4K addresses. I have tried them with vanilla and
custom kernels all 2.6.19+ versions. Results are same on both systems ,
so thats the reason I am thinking that there is some limit in kernel
source tree which I cant seem to find . Really appreciate your help in
this regard.
Thanks,

That's like saying you've got a SPARC. Or a MIPS. Or a PPC.
(I can't infer from your answer whether that is running 32 or 64-bit
kernel, because there are P4s with and without 64-bit extensions.)
