Recent master kernel -and- world?

If this is seen again, truss or ktrace output of dhclient would be helpful.

If you could install a debug dhclient now, in the event it happens
again you could induce a core (or at least gdb the process and get a
trace), that might prove helpful as well.

Why, specifically, does the network stop working, if you can identify
it? Default route? resolv.conf overwritten?

Thanks,
