>Description:
When the system is rebooted uncleanly (e.g., power failure), and you configured ppp(8) with set server=/path/to/ppp_socket, this socket won`t be unlinked by ppp.

So, when you power on the machine, the socket is already in place, ppp can`t bind it (Address already in use) and you cannot use pppctl, unless you manually remove the socket and restart ppp.
>How-To-Repeat:
* Add this line in your ppp.conf: set server=/etc/ppp/pppctl
* Start ppp.
* Unplug the power cable of the machine.
* When you restart it and run ppp, it will be unable to bind the socket.
>Fix:
Add this line to /etc/rc.network:279
rm -f /etc/ppp/pppctl

A better solution would be to put PPP_SOCKET=/etc/ppp/pppctl in /etc/rc.conf and rm -f $PPP_SOCKET in /etc/rc.network:279
