Dear Mark,
sorry for my late answer. I'm still in a hurry. Unfortunately there are
no log files left from October.
But I should say that we had several similar events during the last week
(and from time to time) which
are in coincidence with shutdowns or end in shutdowns (don't know what
comes first).
I could prepare the message logs if you think it's worth. However, not
before tomorrow.
Best regards,
Karl

Dear Mark and Ben,
thanks for your response. We could not find which component in our system may have caused
the "umount".
But since then it never happened again. I think we will go over to a newer
version of the client and then see what happens.
When you first reported this, I focused on the possible reasons for the shutdown, and
inadvertently overlooked the panic/hang that you also reported. But recently while doing
some Solaris testing I discovered a bug in the OpenAFS Solaris shutdown code. Unlike
you, my shutdowns were intentional; but like you, I saw "Failed to flush
vcache" messages and a panic after shutdown. At that point I remembered your email
and realized you had probably encountered the same panic I did. However, the only way to
be sure would be to look for the panic messages in your syslog. If you still have those
(from back in October), it would be helpful to see them.
Regardless, I'm able to duplicate the problem quite easily.
I've opened https://rt.central.org/rt/Ticket/Display.html?id=132689 and I am
working on an upstream fix for this.
Regards,

we experience unwanted "shutdown" events of our OpenAFS 1.6.9 clients under
Solaris 10.
Running this client since October last year without problems on ten Solaris
desktop servers which reboot regularly on weekends, we recently had kind of
crashes on nearly half of these servers in the middle of a week.
The log file (/var/adm/messages) contains kernel messages which look like a
shutdown which seems to be initiated by the afsd itself.
