I have recently had EDT crash on uVAX II / VMS 4.4, and VMS itself crash
on 780 / VMS 4.2 when running EDT from a DECnet terminal over an Ethernet.
EDT gave a memory protect violation and VMS gave a fatal bug check (while
in another process).

It seems that VAX/VMS should protect itself from any computer sitting on
an Ethernet cable, so I don't really blame my IBM PC for the crashes.  But
I suspect the PC might be a "bad neighbor".

(BTW, the crashes do not occur if I "set host" from one uVAX to another,
or if I run EDT from a terminal on a RS232 port.  I was running on the
uVAX with full privileges, but on the 780 with no privileges.  I believe
this made the 780 system manager feel he had been violated!)

I'd like to hear of any additional experiences along this line, especially
involving early versions of DECnet DOS (distributed by DEC for PCs).  I'm
not a system manager tearing my hair out over this problem, just a user
who would like to (eventually) have a bug-free DECnet link between a PC
and a VAX.

Thanks -
