Normally, I expect dhclient to run at startup and then disappear into the background. Today - in the process of diagnosing other troubles - I ran into this from top: last pid: 48344; load averages: 3.30, 2.85, 2.46 up 0+19:50:53 14:17:04 127 processes: 3 running, 122 sleeping, 1 zombie, 1 lock CPU states: 42.4% user, 12.5% nice, 42.4% system, 2.7% interrupt, 0.0% idle Mem: 146M Active, 22M Inact, 100M Wired, 2560K Cache, 60M Buf, 222M Free Swap: 2048M Total, 310M Used, 1738M Free, 15% Inuse, 156K In PID USERNAME THR PRI NICE SIZE RES STATE TIME WCPU COMMAND 226 _dhcp 1 111 0 1528K 268K *Giant 31:04 12.74% dhclient Now I assume "*Giant" means the Giant Lock ... which is another thing I've never seen before. Not for dhclient, and not for anything else. Gut reaction says this is not a good thing. On the other hand my gut reaction has often been wrong. Is there a legitimate reason for this much activity? If not, how do I figure out what's broken? (I'm running FreeBSD 7.0-CURRENT #0: Wed Jan 4 13:41:21 EST 20 but this is as much a question about dhcp as it is about any particular version.) Robert Huff
