I believe OpenBSD's dhcpd is based on ISC's implementation, in which
case:
static entries are in the global scope and independent of any pool
declaration. The error is one of configuration: you've defined static
entries and dynamic pool overlapping = you've told it to use the IP
addresses twice.
At a pinch, the option ping-check, might help you out if your address
space utilisation is not too large.
