DHCP on an old, slow AIX box.

Hi Jeff,

telling you my configuration:

I also have an experimental net for testing purposes with two RS6000 
machines (failover) and dhcpd version 3.1.0 and bind DDNS 9.4.2.
The RS6k is a 43 p model 150 with 384 MB RAM and 375 Mhz CPU.

I don't see those problems you have mentioned, anyway.

Furthermore I have two more RS6k exactly the same hardware with only 
dhcp version 3.0.3 as a failover pair in production environment serving 
more than 5.000 addresses without any probs.

If you want more info, you can contact me off-list.
