PPP won t reconnect

[Franco Vitali]

I search the web for an answer, but i can´t find it. There are only
unanswered posts, and some of them tell that there is a bug in PPP.

I have a production machine with a RELENG_7 and a connection with the cable
provider via PPP.

The problem is that, when the connection drops, PPP remains like nothing
happens, not even a log (even if i plug the ethernet cable). And, ovbiously,
doesn't reconnect. In theory, the daemon must reconnect in "ddial" mode.
What I am missing ?
