Thanks for replying. I was just doing tcpdump and not looking at the log

I have an automated process that updates the included
dhcpd.registrations and restarts the dhcpd service.

I adjusted the dhcpd lease times and was able to see that it will

So my problem is with the short lease times and having to restart dhcpd
when the dhcpd.registrations file is updated. This is causing for short
periods of dhcpd downtime and no replies to dhcprequests. Which is what
I use to automatically swap someone over to a new pool. This lack of
response causes some clients to hold onto old leases.

I'm starting a new message asking for a better way of loading changes to
the static hosts file.
