Already did this in single use mode.  It is looking more and more like
someone was port scanning (again) and by chance the other machine locked
up 15 minutes later.  There is no evidence of even a port scan on the
locked machine. Or even connections from the scanned machine.

I think this cracker was just port scanning.  I don't know what caused
the lockup.
