We Ran SATAN here against several of our Unix machines, all passed. I
then tried it agains one of our AXP/VMS workstations running Multinet.
It crashed.
After the machine came back up we tried it again.
It passed fine.
I did Heavy tests both times. At first glance it appears that the AXP
just ran out of memory.
