problems with SSH after last patches

Hello, trough hollidays I've been applying last patches for multinet and
found that after that I'm having problems with SSH, stop working after
some time. the error in the SSHD.LOG says
"Failed to get handed-off socket: errno 6"

At the same time I've applied some VMS patches like:

VMS83A_UPDATE V5.0
VMS83A_SYS V6.0
VMS83A_ACRTL V4.0

The last Multinet applied patches have been:

KERNEL-UPDATE V6.0
UCX_LIBRARY_EMULATION V6.0

I don't know if the problem was with Multinet or VMS patches, but prior
to this changes SSH was working fine, and just after installing the
patch was also working.

Even if I stop SSH master server and Multinet Server and restart them
SSH continues without working, I need to reboot the system and SSH works
again for a time.

Can I activate some DEBUG to check where is the problem.

Regards
Juan C. Blanco

This message from the Info-MultiNet archive seems relevant:

http://www.multinet.process.com/scripts/mxarchive/archive_search.com?TEXT=R52168-57220-mail%24archives%3A%5Binfo-multinet%5Dinfo-multinet.2007-12

If that link doesn't work for you, it was a reply from Dan O'Reilly on
Dec 5, in response to the original question posted by Yehavi on Nov 6.
The subject of the thread was:

SSH daemon fails with "Failed to get handed-off socket: errno 6"

Sounds like a patch is in the works.

This is a known problem, and the upcoming ECO's will address it. The
source of the issue is with one of the VMS patches that increased the
number of device unit #'s to 65535. Up to this time, they were limited to
32767 (a signed word) and now, of course, it can go to an unsigned word.

The only cure at this time is to reboot or to back out the offending VMS
patch (the README for the ECO's should tell you which one caused the problem).

At the time, Yehavi solved by backing at VMS83A_SYS V5.0. If Juan
skipped that one and just applied V6, presumably that could be backed
out as well if there weren't things there that were crucial.

Any guesses as to how far away the MultiNet ECO that addresses this is?

Soon (next few days), hopefully.
