I tried both versions. Everything was fine on 8.2. Everything is still fine on the failover sibling still running 8.2 with the same config (the only difference is that it's a master). Top: last pid: 44964; load averages: 2.97, 2.43, 2.40 up 3+19:54:21 11:56:18 247 processes: 3 running, 244 sleeping CPU: 4.0% user, 0.0% nice, 23.7% system, 23.0% interrupt, 49.2% idle Mem: 292M Active, 55M Inact, 3396M Wired, 65M Cache, 418M Buf, 83M Free Swap: 8192M Total, 1696M Used, 6496M Free, 20% Inuse PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 44604 dhcpd 1 92 0 24664K 4928K CPU2 2 2:29 69.87% dhcpd 44938 dhcpd 1 4 0 20696K 7544K RUN 1 0:11 30.96% dhcpd (these are -6 and -4 daemons, running only one of them doesn't help either). Also what is weird: sibling under 8.2 eats 3% after starting daemon, then this number is decreasing to 0%; 9.0 eats 20% after starting, then this number increases to 70%. >How-To-Repeat: Get a FreeBSD 9.0, install any of net/isc-dhcp4*-server ports, run it. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
