Hello,
I'm able to obtain a running VMS session with my VAX (simh). All but
keyboard run fine. I only have an error in 'host'_1.log file:

I don't know which image returns this access violation.

Would turning on image accounting for a short time give you this information if you look at the image exit status in the accounting logs ?
on image accounting and repeated the above procedure. Look at the exit
status of the images until you find the ACCVIO one. That should tell you which image is exiting with an ACCVIO status.
Don't forget to turn off image accounting when you are finished to avoid filling up your disk with accounting logs. :-)

To be clear, there is no clear-text accounting log file on the system.

If it is an older busy system, then no selection will result in

Shouldn’t “stat” and “img” be initialized to something like “null” or
“undef” (or whatever the Groovy equivalent is)? Unless you’re assuming they’ll always be defined for that record type.

I have tried
$ accounting /image=sys$manager:decw$wsinit
before logout/login again.
And yes, sys$system:decw$wsinit (at least on Eisner) is linked with /notraceback so you only get a register dump and no information on the
call frames.

They should (Groovy uses null).
An image activation record should always have a resource
and imagename pack. But good defensive programming style
say to initialize anyway.
Sorry, pressed snd too soon ...

That looks like a clue. Why is it expecting a mailbox device and

There is probaly a SET TERM/INQUIRE in SYLOGIN.COM or LOGIN.COM, which

If run in BATCH oder NETWORK mode, SYS$INPUT points to the disk, on

You already know their exact contents from the register dump.

set rad hex

The CALLG uses an argument list, which is on the stack. Maybe you can
find something useful on the stack.

In the log file, is there any message about not being able to create a

Nope 🙁
You connect to XDM on the VAX, correct?
That is, DECW$WSINIT runs in the
context of the TCPIP$XDM user. In case there is a resource problem, it
may not be possible to write a process dump, just because doing so
requires resources, too. It's not obvious whether that is the case or
not. The fact that you get a process dump for the same ACCVIO when
running DECW$WSINIT interactively, indicates that the underlying problem
for the ACCVIO is not a resources problem.
I have set accounting before posting. Strangely, all ACCVIO are
not loggued.
I'm not sure I understand what you mean.
