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,
-d

I am getting after initial successes some errors:
"rtnl_talk(): RTNETLINK answers: Cannot allocate memory"
and
#ip addr | wc-l is 8194.
I'd be surprised if it was 4096 on x86 and 8192 on x86_64...
Missed to mention: the CPU is Pentium-4.
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.)
