Debugging a Portmaster

My only PM2 with ten ports running 3.3.2c1 locked up pretty tight today.
It was still generating a DTR signal to the modems, but it wouldn't give a
login prompt after answering, and I couldn't access it via the ethernet
port.
I suspect some sort of DOS attack against the unit.
Isn't there a debug setting that would show low memory, mbufs, and other
problems that might indicate an attack in progress? All the debug
settings on Livingston's web site don't seem to be quite what I want.
