PPP oddity with 6.2-RELEASE

Thu Jan 18 13:29:07 UTC 2007

This system has been running 5.x for over a year with no problems.
Last weekend, I cvsuped, and did buildworld using RELENG_6_2.
This machine is set up to connect to my isp via PPPOE upon boot.

Now, when it boots, it does the connection fine, and TUN0 is set up.  
But, immediately after that, it starts another PPP process, and tries to 
reconnect using TUN1.
It keeps re-trying until I kill the second pid.  Nothing has changed in 
my config files.
Any ideas???

Here is a sample from the /var/log/ppp.log:
