BOOTP from dynamic client and no dynamic leases

[Wizumwalt]

I've got a dhcp problem where a node I'm putting online is unable to get an ip. It would seem that a different node already has it according to the dhcpd.conf file, but none of the nodes on my little cluster have this ip. So I believe the problem is that I can't get an ip that seems to have already been taken, but I do not see where. I believe this is all BOOTP since I have hardwired the ip to the mac for each machine as shown in the dhcpd.conf file further below.

Here's the output error from the messages log.
