I have some kind of conflict with the NetworkManager and dhcdbd and dhclient. Basically, everytime I shutdown, the dhclient doesn't get killed until last even though the network configurations are supposedly cleaned up. As a result, I get this send_packet network unreachable error when some last resort TERM is sent to all running processes.

I realize this isn't all that much information to diagnose the problem, but if anyone has seen something similar or knows in general how dhcdbd and the NetworkManager and dhclient are supposed to function, that would be a start.

Okay, here's my syslog which really highlights the problem. Basically, I need to know whether dhcdbd is supposed to start dhclient or just connect to an already running dhclient. If dhcdbd runs dhclient, then maybe I should disable my rc networking script, if dhclient is running already, then maybe I should move the rc networking script forward. Or maybe its a totally different issue.

But you can see in the below script that things are not starting up in the proper order. Similar issues happen on shutdown.
