I have a failover pair of DHCP servers running 4.4.2-P1 that handle a DHCP for a very large wireless network (>75k devices active at any time). The leases file on these boxes is around 200 megabytes. The problem I am having is when I need to make a change and restart, DHCPD takes over 25 minutes to start giving out addresses. I assume this is due to the large lease file. I see that there are tons of leases in the file that are “binding state free” that in some cases are months old. Are there any suggestions to improve this situation?
