OK, I changed the range so as not to conflict with the fixed
addresses. Still "no free leases."
range 10.24.7.100 10.24.7.254;
I also tried putting in the uid statements suggested elsewhere:
option dhcp-client-identifier "\0pos_30";
option host-name "pos_30";
The byte list is an exact match for the 7 bytes the client is sending
in the DHCPDISCOVER packet, but dhcpd -t reports
mdb.c(319): non-null pointer
and the server still reports "no free leases."

Normally I use the MAC address and be done with it, but in this case I
have an externally-imposed requirement to use the client-id only.
