I have seen more than one person comment that this condition occurs on the busiest Portmaster.
1) Are the incoming phone lines on a rotary so that load balance occurs across all the ports?
2) Did this problem occur in ComOS 2.x or just started in 3.x?
Observations from my own syslog
-------------------------------
I grep'ed through my syslogs and found...
Syslog Dates sessions dest 0.0.0.0
--------------- -------- ------------
930402 - 940812 10530 0
940812 - 950918 47891 5
950925 - 951017 1782 0
Since only 5 sessions were ever noted, take a look at them(PM name and user changed to protect the innocent).

Note!
-This user account is PPP. Yet, what is this ipx referrence?
-He hit repeatedly hit the same ports.
-He finally made it into port S1(see below).

Just a few questions and observation to throw out to see if it sparks any ideas.
