utauthd (3.1 -03) on Sol10 u2 crashing?

Hello!

I have a X4200 with Solaris 10 update 2 and SRSS-3.1 with 120880-03 and all other patches available to updatemanager applied.

The firmwares of the SunRay-1 terminals has been updated with utfwsync.

After the machine has been running for about 12 hours all terminals are unuseable. They just have the blue screen. All processes are still running so it seems like the sessions are still there... somewhere...

They are all able to get an IP adresses but will not reattach to the sessions.

The machine quickly gets a load of 2.5 (2 CPUs installed) and will not drop below 2.0. All load seems to be generated in the kernel. No processes seems to create the load in userspace.

utrestart do not work. It seems like utauthd will not be able to restart because the instance already runing cannot be killed and therefore restart fails (it is already running on that port 7010).

"sync; sync; init 6" do not reboot the machine either (due to unkillable

processes (even with -9)).

If the machine is left untouched in a couple of days it will end up with 300-400 defunc processes and a load about 4.0. Occationally the load can get near 100!

Could this be a problem in utauthd, or?

Am I the only one experiencing this behaivour?

Are there any way that I can help in debugging this issue?

Best regards,

- Morten Green Hermansen, Fanitas

ughh -- all you say sounds terrible. just right now, i've updated 2 ray servers to sol10u2!

one of them is running for 15h, the other one for 30min...

the servers are running on sparc machines (patches applied, incl 120879-03). i really hope that what you describe is a x86 problem only!!

at the moment everything looks fine for me,

AFAIK nobody else has reported anything like this. It sounds like a kernel problem but it would still be interesting to see a thread dump from utauthd when it is in this condition. Please do 'kill -3 <pid-of-utauthd>' and look for output in /var/opt/SUNWut/log/auth_log.)
