tcpip$ssh_sshd2 crashes on some users
The tcpip$ssh_run.log files for the disconnecting session show an ACCVIO. I'd guess it's having difficulty looking for the user's ssh2 directory.

Re: tcpip$ssh_sshd2 crashes on some users
Second thing is whether the offending disk is ODS-2 or ODS-5 and is that different from the disks that work?
Third thing is whether the offending disk and the non-offending disks are on the same controller (and is one a SAN and the other local)?
Fourth, I've seen ACCVIO terminations on previous versions of SSHD. The folks that hit us the hardest are those who are either CAPTIVE or RESTRICTED, and for which their command shells trap all errors and log those people off instantly (rather than to allow the shell to abort and let these users see the DCL prompt.)
If you turn up logging level (see, for instance, file SYS$SYSTEM:TCPIP$SSH_RUN.COM as a place to turn up logging level), see what it is trying to do just before it barfs.

Re: tcpip$ssh_sshd2 crashes on some users
like.
It did several tests with a dummy account.
Environment:
physical disk: $21$dka0: (label USERS)
directory tree: [trial9.level1.level2.level3]
logicals:
DISK$USERS $21$DKA0: [conc,term]
BSDISK $21$DKA0:[TRIAL9.] [conc,term]
BSDISK_LEVEL1 $21$DKA0:[TRIAL9.LEVEL1.] [conc, term]
Login default directory tests:
bsdisk_level1:[level2] PASS
bsdisk_level1:[level2.level3] fail
bsdisk:[level1.level2] PASS
bsdisk:[level1.level2.level3] fail
disk$users:[trial9.level1.level2] fail
disk$users:[trial9.level1] fail
disk$users:[trial9] PASS
$21$DKA0:[trial9] PASS
$21$DKA0:[trial9.level1] fail
In general, the accounts that fail use a concealed device logical with 2 levels
in the concealed directory. The test with bsdisk_level1:[level2] should have
failed if it was just simply number of directory levels though.

Re: tcpip$ssh_sshd2 crashes on some users
please check whether the concealed devices (as specified in SYSUAF) are defined correctly.
They MUST be systemwide, and MUST be /EXEC mode.
And, while not for any tcp related stuff (Oracle DBMS to wit), I _HAVE_ seen CLUSTERwide LNMs being NOT honored, so that MAY be worth checking as well.

Proost.
Have one on me.

Re: tcpip$ssh_sshd2 crashes on some users
If you alias [alias3] and [level2.level3] to the same directory, the former works and the latter gets the ACCVIO.

Re: tcpip$ssh_sshd2 crashes on some users
For instance, the version I'm looking at would attempt to do some define/process commands based on a translation of spec.
TCPIP$SSH_DEVICE:[TCPIP$SSH]
See if there is problem with that definition and whether you can reliably look up
SYS$SYSTEM:TCPIP$SSH_SSHD2.EXE
which is also part of the SSH_RUN file.
Finally, look at all of the TCPIP$SSH_RUN.LOG files to see if they show funkiness before the Access Violation. Like, maybe, warnings that wouldn't abort the implied script but that might indicate something else isn't defined properly.

Re: tcpip$ssh_sshd2 crashes on some users
What is in SYSUAF for the DEFDEV and DEFDIR values for the working and non-working accounts?

Re: tcpip$ssh_sshd2 crashes on some users
Occasional ACCVIO in SCP when the username and the owner-identifier string don't match - the case in question where the USERNAME was JOE and the account's identifier was [USERS,FRED]. Could this apply to the ones who fail?
