Well, it happened again slightly over 14 hours this time.
9:25PM up 14:09, 4 users, load averages: 1.03, 1.39, 1.93
After killing and attempting to restart pppd, I gleened the
following from the messages file. Any clues as to what is
happenning? This message was logged when I attempted to
restart the pppd. Restarting pppd caused the modem to drop
carrier.
