I applied the patch last night and we have not had any reports of
26d's today on kiosk sessions.
This patch seems to have helped. I'll deploy the patch to our other
servers and post an update later on this week.

It's possible you'd get a 26D. I've never seen this actually happen,
but was guessing you wouldn't that since the X server never died. I
didn't see a mention of OSD codes in the bug report.
So, yeah, give it a try. Can't hurt.

Craig,
Thanks for looking into this.
We have been running on Nevada b130 and been getting 26d's on kiosks
and user sessions.
I'll give this patch a try and see if it improves things on the kiosk
side of things.

Hi Karl,
Only applies to SRSS running Kiosk mode under OpenSolaris, nothing
to do with slow shut down of OpenSolaris VM's used in our VDI product.
It has to do with signal handling in the kiosk pam module.
Situations could occur where a session ended, but the methods used
to tear down the session could not be invoked due to the signal not
reaching the pam_kiosk that drives the tear down process.
If you had SRSS running Kiosk mode under OpenSolaris, you'd see
messages like this in the log files: "Could not terminate session
for user utku0"
End result is you'd wind up with sessions whose primary application
exited, but Xserver doesn't terminate, the kiosk XSession script
keeps running, etc. Since other tools rely on the pam_kiosk signal
handling, even trying to use kioskrestart to kill it down, it will
fail.
From an end user standpoint, I believe the DTU's would be stuck in a
limbo state with nothing displayed but a black screen (i.e. not a
OSD code 26) since SRSS still thinks the session is valid.
While OpenSolaris is an unsupported platform, the fix resulted in
better signal handling of pam_kiosk.

Can someone provide more colour on the following fix:
6814845 kiosk sessions do not terminate properly on OpenSolaris
Thanks
