okay. have you done a shutdown -r now since you fiddled with the upstart scripts?
any chance they are cached? I have no idea.
Connection manager sounds a lot like a wifi thing. I would have to dig around in my 3 to check I suppose. perhaps killing some likely processes could give me some helpful log output.
(you would want a seperate shell for this ideally)
tail -f /var/log/messages &
and then go killing stuff in the other shell
See what process names spawns that log
or grep -r "Connection Manager" /var (and other places) to see if you can dig up some log configs...(This may hang your DX badly)
Those would be my tests. in the absence of better info.
