All, Were these patches eventually fed into the next iteration of the net-snmp release?

The code does assume that the number of CPUs is constant. > Any ideas how to fix? One option would simply be to skip any "new" CPUs. The attached patch is untested, but should handle that. (Though I'm not sure whether it would work better with 'break' or continue - you should experiment). If you change the 'break' statement to call 'init_cpu_kstat()' instead, then this should cope with updating the list of CPUs. Obviously, that's even more untested than the basic patch, but give it a go and let us know how you get on.
