Jason, you do not want to involve Support, but you would have solved it by
now if you had. This is not a support channel.

I will tell you one thing for free: you should be looking in the
netmon.trace file
to see what netmon is doing when it hangs up and dies. You can toggle
tracing
on with 'netmon -M -1' and off with 'netmon -M 0'. If it never starts
talking, then
it is too busy to get the message. In that case, turn it on at startup by
setting it
with daemon configuration.

Reading the netmon.trace is a whole lot more fun than reading the core
report.

Cordially,
