To put closure to this, the problem is documented in the TCPIP056.RELEASE_NOTES; albeit, the stack dump's footprint is completely different.

On this system, the SYSTEM account (UIC:[1,4]) and the SYSTEM identifier (UIC:[210,4]) did not match. This is called out as being problematic with ssh in the release notes. I fixed the SYSTEM identifier with:

$ MCR AUTHORIZE MODIFY/IDENTIFIER SYSTEM/VLUE=UIC=[1,4]

BTW, once again my issue was solved in comp.os.vms. This forum would be much more useful if I didn't first have to go digging through old log books to find the cryptic username and then password which I can't ever remember because I'm forced to use a stupid 6-8 characters with a numeric.

Your forum email address works, but it's also case sensitive.

You can also search the forum for your name, find one of your post and click on your name. Then, if you look at that page's URL you'll see userId=CAnumber.

Log in and click "My Profile", then click "view or modify forums profile" to see your forum email address.

Use either the CA# or your email address.
